About The Book

“Part (possible) murder mystery, part deep dive into out-of-control social media addiction, and part sleight-of-hand trick by the author...terrific.” —The New York Times

The author of The Family Plot brings her signature “taut, emotionally charged, and propulsive” (Jeneva Rose, New York Times bestselling author) prose to a twisty novel about a heart transplant patient who becomes romantically obsessed with her donor’s husband.

She has his wife’s heart; the one she wants is his.

Rosie Lachlan wants nothing more than to find The One.

A year after she was dumped in her wedding dress, she’s working at her parents’ bridal salon, anxious for a happy ending that can’t come soon enough. After receiving a life-saving heart transplant, Rosie knows her health is precious and precarious. She suspects her heart donor is Daphne Thorne, the wife of local celebrity author Morgan Thorne, who she begins messaging via an anonymous service called DonorConnect, ostensibly to learn more about Daphne. But Rosie has a secret: She’s convinced that now that she has his wife’s heart, she and Morgan are meant to be together.

As she and Morgan correspond, the pretense of avoiding personal details soon disappears, even if Rosie’s keeping some cards close to her chest. But as she digs deeper into Morgan’s previous marriage, she discovers disturbing rumors about the man she’s falling for. Could Morgan have had something to do with his late wife’s death? And can Rosie’s heart sustain another break—or is she next?

Excerpt

Chapter One CHAPTER ONE
At first, I mistake the blood for sequins. Bright red sequins sewn onto a white gown.

Then I spot the blood on my thumb, seeping from a cut near my cuticle. I’ve been scraping at it, I guess, tugging a scrap of skin as I studied Morgan Thorne’s latest Instagram post.

He had Chinese takeout for dinner. Dipped his dumplings in ketchup. Does anyone else do this? he asked in the caption. And the answer is me. I do. I’ve gotten strange looks for it all my life.

As I lingered on that post, I stopped seeing it for a moment. Instead, I saw us together, me leaning across a table to extend a dumpling toward Morgan, who took a bite, moaned with pleasure, before licking his lips, tongue wet with grease. Then it was my turn. He teased me first, inching the dumpling closer only to pull it away when my mouth tried to clamp around it. His smile was wild. Wolfish. He stared at me like I was the meal.

But then the red. It bloomed in my peripheral vision. I looked at the sequins—no, not sequins—and my eyes snapped wide.

Now I realize I must have touched the gown, stroked the lacy fabric as my mind lured me into fantasy. The dress is a Maggie Sottero fit and flare we received last week. My parents—my bosses—will not be pleased.

I tuck my phone into the pocket of my black dress and suck the blood from my thumb. Then I fold the gown over my arm to haul it down to Fittings.

“One of my brides had a nosebleed,” I tell our seamstress, Jane.

Jane tsks at the gown, even grabs the fabric, squinting at it through her glasses.

“She felt so bad,” I add. “My bride.” I look at my shoes, sorry to give Jane this extra work to do; I know her son is visiting from New York.

“It’s fine, Rosie.” As Jane pulls the dress off my arm, her gaze catches on my thumb. Fresh blood pools in the nail bed.

“I’ll take care of it,” she adds. With one hand, she slips me a Band-Aid from the top drawer of her desk. Then she winks—and I flinch.

Brad was a winker.

I take a breath, attempt a smile. It baffles me, still, how something so tiny, literally the blink of an eye, can yank me back to him. Or—not him, I guess. The dark pit of it all. The days in bed. The tangled spirals of grief and shame. The pain in my heart that started as a metaphor, before it worsened into a symptom. Then, always, the smell of the hospital: citrus and urine. The hope, even then, that he’d hear what happened and return to me.

Back upstairs, I march through the front room of the store—all sleek gray hardwoods, subtle blush walls, ivory couches and armchairs—to lock the door. Without the chirp and chatter of brides, the salon is the kind of quiet I can feel in my head, a pleasant pressure after a packed day of appointments. The second it turned eight tonight, I let Marilee and the other consultants go, tiny thanks for all their hard work, so there’s not even the sound of their heels clicking across the floor as they sweep and straighten, tidy and tally.

Thumb freshly bandaged, I flick through a rack of gowns, ensuring the bodices all face to the left. I pivot to a mannequin, reaching to readjust a silky strap, when there’s a knock behind me—one so frantic I clutch my chest.

A woman stands outside, pressing a garment bag against the door, Just Say Yes’s rose gold logo embossed on the fabric. Her lips open and close, fogging the glass with muffled words.

We’re closed, I mouth, but that just makes her knock even harder.

Her eyes, red and puffy, shine beneath the light outside. Her cheeks are streaked with mascara. Her shoulder-length white-blond hair is nested and knotted against one side of her head, as if she’s been burrowing into pillows. Please, her lips say—and I recognize something in her. Despair. Desperation.

I hurry toward the door to let her in.

“Are you okay?” I ask as she steps inside. She hunches to the left, weighed down by her garment bag. “Here, let me—” I take it from her, hang it from a nearby rack.

“Thank you,” she says, almost breathless. “I’m sorry to just—I need to return my dress.”

“Is there a problem with it?” I unzip the bag a few inches, and the woman winces like I’ve squeezed lemon on a cut.

I peer inside to find a Stella York ball gown, and right away, I understand her panic. It’s a gorgeous piece, but one I never would have pulled for her. The voluminous skirt would swamp her small frame, and the bustier top would shorten her torso. She’d do much better in a fit and flare. Actually: she’d look amazing in the Maggie Sottero I bled on.

“No, the dress is—my dream,” the woman says.

Ah. This happens a lot. A bride comes in with a specific vision, a style they’ve admired on tall, hanger-thin models, and despite the consultant’s efforts to steer them toward more flattering dresses, they can’t let go of the fantasy, end up ordering a gown they fell in love with online before they ever saw it in real life.

“It’s just—” The woman swipes at her errant makeup but only smudges it more. Her cheeks blush with kohl, giving her a gray, decomposing look. “I don’t need it anymore.” She attempts to smooth her hair before dropping her hand to her side. “My fiancé broke up with me. The wedding’s off.”

It’s so fast: the dizzy whirl of memories. My reflection in a full-length mirror. The door behind me opening. Brad’s freshly shined shoes entering the room.

“And now I’m stuck with— This dress, it’s—”

My vision prickles at the edges. I blink the darkness back.

“Every time I see it in my closet, it’s like—”

“Like seeing a ghost,” I say.

The woman’s face opens—eyes widening, lips parting—like my response unlocked something inside her. “Exactly,” she whispers, fresh tears tumbling onto her cheeks.

Steady as I can, I walk to an end table, pluck a tissue from the box we keep there for parents who cry at appointments. “Here,” I say, handing it to her. Then I pick up her garment bag, carry it to reception, and drape it over the counter. The woman follows, dabbing at her eyes.

“Sorry,” she says. “I know I’m a mess. I’ve been a mess for days. This week has been—” She shakes her head, no words for the horror of watching her future dissolve. “But you’re right. This dress is a ghost. Thank you for putting it that way.”

I shrug off her gratitude. “I just… know what it’s like, owning an unused gown.”

She freezes, tissue still held to her face. “You’ve gone through it too.”

The dress that haunts my closet is a Casablanca A-line with a beaded lace bodice, cap sleeves, and sweetheart neckline. The satin skirt is both dramatic and simple—no appliqués or other embellishments, just a stunning chapel train. The second I saw it, shimmering on its hanger, I knew it was The One. Same as I knew Brad was.

I click the keyboard to wake the computer, force my voice to be strong. “What’s your name, so I can look it up in our system?”

“Edith Cole,” she answers, and as I type it in, I feel her studying me. She leans forward to whisper: “How did you get through it?”

She cringes at her own question, taking a step back. “Sorry. I hope that’s not too intrusive, it’s just… As you can probably tell”—she gestures toward her face, then to her T-shirt and sweatpants, too—“I’m still in the Cry All Day phase. I’d love to know what other phases are available to me.” She chuckles wetly, a bubble of snot escaping her nose. “Oh, gross, sorry.” She blows into her tissue.

“Well, there’s the Gilmore Girls phase,” I say, thinking of my non-Brad breakups. “Doesn’t matter how many times you’ve seen it; the Gilmore Girls binge is an important part of the process.”

“I’ve actually never seen it.”

“What! Oh my god, you must. Half the characters are kind of insufferable, but that doesn’t matter. It’s actually part of the fun.”

Edith nods. “Love to hate an insufferable character.”

“Exactly.” I click my nails on the counter. “Then there’s the Horror Movie phase. The bloodier, the better.”

She scrunches her nose. “Those tend to give me nightmares.”

“Heist movies then. The point is: nothing romantic.”

“Got it. What else?”

“The Danish for Dinner phase. I recommend two at once: one raspberry, one cheese. It’s got all the major food groups: fruit, protein, dairy, joy. Sweet Bean next door”—I gesture toward the café that shares the L-shaped plaza we’re in—“has the best Danishes.”

Morgan Thorne loves them, too.

Last Sunday, he posted a photo from Sweet Bean: his laptop on one of their tables, an open notebook beside a Danish and cappuccino. One does not simply go to Sweet Bean and not get a Danish, he’d captioned it, and I wished I’d been working that day so I could skip next door, brush by his table, then accidentally—

“I’ll definitely get some,” Edith says. “This is great; I should be taking notes.”

“Oh, and don’t forget the New Hair phase.”

“Ah, yes. A classic.”

“For good reason. Breakups always make you feel like you have no control, you know? Well—they do for me, anyway. I’ve always been the one getting dumped. So changing your hair is this tiny thing you can do to feel some control again. It’s like training yourself to become a new person.”

Edith stuffs her tissue into her pocket. “Is that why yours is pink? Because your wedding got canceled?”

I finger the ends of my hair, the waves I added to it this morning still holding after eight consultations. “Uh, no. I did this… a while after that.”

Seven months after.

Four weeks out of the hospital.

My best friend, Nina, drove me to the salon, helped me pick out the perfect shade. And as the stylist swept the dye into my hair, I watched my old self disappear in the mirror. No longer the woman who’d crumbled so completely after Brad that not even my breakup phases could piece me together again.

New heart, new hair, new me, I said to Nina as we stared at my reflection. But when she hugged me after, her chest pressed to mine, I felt Brad’s absence in every inch of my incision.

“Oh,” Edith says. “Well, it’s a great color.”

“Thanks. It’s very cotton candy, I know.” This has been my refrain, the last eleven months, whenever someone mentions my hair—safer to pretend I’m in on the joke in case they think I look crazy. In truth, I love its gentle pink, a shade inspired by the spray dye Nina used last Halloween, when she dressed as cotton candy herself. All that night, I kept holding her hair up to mine, enamored of the color, despite how it clashed with my evermore-era Taylor costume.

“Nothing wrong with cotton candy,” Edith says. “And that means something coming from me—when I was like ten, I puked all over this boy I liked after eating too much of it on a field trip. Totally traumatizing.” She grimaces at the memory. “But is it weird if I admit the puke was a pretty color?”

I laugh. “My childhood puke food was Twizzlers. Right after a friend’s birthday party. The back of my mom’s car looked like a bloodbath.”

As Edith smiles, her eyes brighten, despite the shadows of smudged mascara.

“Anyway,” I say, “I’m so sorry this happened to you. The dress, your wedding.” I look at her order on the monitor. “Do you want me to apply the refund to the card we have on file?”

“Wait. You’re actually letting me return it?”

“Of course.”

“Oh, wow, okay. I came here thinking this was a long shot, but”—her eyes dim as they drop to the garment bag—“I had to try.”

We do have a no-return policy. If my mom were working today, she would advise Edith to sell the dress online. But I’m taking advantage of a different policy, one specific to me as the manager: every four months, I can comp one bride a dress. Maybe it’s less a policy than it is my mother’s way of managing me; I used to beg her to let me comp gowns all the time—for brides with money trouble, or terminal illnesses, or recent losses of loved ones. Can’t we do this one small thing?

Rosie, your heart is so soft, she’d always tell me, in a way that sounded like a warning, and I’d picture my heart as a giant wad of gum, malleable enough for someone to chew.

But after my transplant, my mother never said those words again, too spooked by how soft my heart had actually become. Instead, she gave me my new policy—an effort to make me happy, I think—with one stipulation: the dress must be under fifteen hundred dollars.

Edith’s cost thirteen fifty. I click the button to initiate the return.

“Refunds are rare,” I admit, dragging the garment bag off the counter and hanging it from a rack behind me. “But we allow them in certain cases.”

I just didn’t intend to use my second comp of the year so soon.

“Wow,” Edith says. “Thank you so much.” She shakes her head through a tearful smile. “I’m so grateful.”

“It’s no problem.”

Edith wipes at her cheeks. “How many Danishes do you think I can get with thirteen hundred dollars?”

As I laugh, Edith picks at her sleeve, shifts on her feet.

“What is it?” I prompt, sensing she has more to say.

“Nothing, I was just—” She fidgets with the canvas tote slung over her shoulder. “Would you want to hang out sometime, maybe? My friends have been great this week, but none of them have actually been through this, and it’d be nice to talk to someone who’s… made it to the other side? Plus”—she shrugs—“you seem fun.”

It’s not butterflies I feel in my stomach, not that half-sick flutter I get when I look at Morgan’s photos or reread his message, but it’s still something winged and wonderful.

“I’d love that,” I say.

I’ve kept my circle small as I’ve healed—mostly just Nina, my parents, my sister and brother-in-law—but it’s been a year since the hospital. I’m already opening myself up to love again; why not friendship, too?

“Yeah?” Edith says, surprised and almost giddy, as if she’d been expecting me to say no. “Awesome! Can I give you my number?” She stops to laugh at herself. “God, I sound like I’m dating again already.”

I laugh with her. “It’s good practice! And yeah, let me get my phone.”

I slide a key off its magnet under the counter and unlock the drawer where I store my purse. I plop the bag onto the counter and rummage through it, taking out items—lip balm, compact, wallet, book—as I dig for my phone.

“Sorry,” I say. “I have way too much stuff in here.”

“Oh, I’m exactly the same,” Edith says, indicating her bulky tote. “I treat mine like it’s half purse, half garbage can.”

My chuckle stops short when I reach the bottom of my bag and remember my phone is still in my pocket.

“Oh. Duh,” I say, pulling it out. I look at Edith, waiting for her to recite her number, but her gaze is stuck on the mess I’ve made of the counter.

“You like Morgan Thorne?” she asks, reaching for the paperback I tossed from my bag. It’s Someone at the Door, the thriller that launched Morgan’s career six years ago, spent eighteen months on bestseller lists, earned a splashy film adaptation. I read it when it first came out, but I plucked it off my overstuffed bookshelf this morning, intent on revisiting it on my break. Still buzzing from Morgan’s message, I was hungry for more of his words. More of his stories. More of him.

“Um, yeah.” I finger the book’s cover. “I like him a lot.”

It was Nina who first suspected our connection. She was there, working in the ER, when Daphne Thorne was brought in. There to hear the hurried discussion about her organs—the ticking clock of transplantation. There, days later in my hospital room, to say, I know this is a hard-core HIPAA violation, but… I think your heart came from that author’s wife.

Now I know she was correct. As I sat on my bed last night, reading Morgan’s response on DonorConnect, I grew almost dizzy from all the details he confirmed. A writer in a Boston suburb. Thirty-eight years old (in March, he posted a photo of him and his best friend digging into a cheesecake on the floor—Celebrating my thirty-eighth birthday by re-creating that one Friends scene that’s always made me salivate). And then, the clincher: Sickle. A cat I’ve adored since I first started studying Morgan’s Instagram. Initially, I’d done a deep dive on his profile because I’d been curious about Daphne, who had no social media of her own, and whose elegant but spare obit offered scant details: loved poetry; taught English at Emerson. But the more I searched Morgan’s socials for specifics about his wife, the more I realized that, even if Daphne wasn’t the person who saved my life, Morgan was someone I was meant to know.

I, too, have salivated over that Friends episode; a few years ago, it even inspired my statewide Quest for the Perfect Cheesecake. I listen to the same music Morgan uses in his Instagram Stories, rewatch the same movies he references in captions. And once, he wrote that Taylor Swift is the Sylvia Plath of our time, a sentence that had me swooning.

We have so much in common—connections that shimmer between us like starlight in constellations. So as soon as I read Morgan’s message, I felt so potently what I could only hope for before: fate is nudging us together.

“Do you like him, too?” I ask Edith.

“Oh, of course. I work at the Burnham Library, so liking Morgan Thorne is basically a condition of my employment.”

I laugh, even though it’s probably not hyperbole. The library has a dedicated nook for Morgan’s three novels, adorned with a placard referring to him as “our hometown hero.”

“Isn’t it so sad about his wife?” Edith says—and my smile slips. “One of my co-workers was really close with her, and she’s still shaken up about it.”

Deep in my core, there’s a punch of guilt, a reminder that my being alive is at the cost of other people’s grief.

“Yeah, it’s—awful,” I force out.

Edith nods, her mouth a straight, sober line. “I guess it puts my problems into perspective, right? Like, at least my fiancé only dumped me. At least he didn’t crack his head open and die.”

My eyes widen as she continues.

“Actually, he might deserve something like that.” She laughs, weakly, before gasping. “Oh god, that’s dark.” Her gaze dips from mine, self-conscious again, as she nudges her chin at the phone still clutched in my hand. “You sure you want my number?”

I assure her I do. I know better than most the way dark thoughts intrude, the way a broken heart can break your brain a little, too.

Once Edith’s number is in my contacts and I’ve texted her mine, she scrambles through a series of thank-yous and apologies before rushing out of the store. I return to my phone, reflexively open Instagram, and revisit Morgan’s post about his Chinese takeout. Then I switch to my Notes app, add another bullet point to the document titled “MORGAN THORNE.” Eats his dumplings with ketchup, I type, right beneath my most recent entry: Thinks the best pet names are plural nouns.

Back on Instagram, I read his caption again. Does anyone else do this? Normally, I don’t look at the comments—they only remind me there are others who might feel a connection with him too—but this time, I scan the responses, as if to prove I’m the only one who shares this particular quirk.

A few people have written variations of lol gross. Others are less opposed: I don’t hate the idea, or We stan a trendsetter.

But it’s a comment from four minutes ago that freezes my thumb mid-scroll.

The only food you should be eating is the kind they serve in prison.

I frown at the words, then open the replies to find I’m not alone in my confusion. Someone’s responded with three question marks, to which the original poster—their handle a chaotic string of numbers and letters—has answered: His wife’s death wasn’t an accident.

My head rears back.

The comment has nine likes but only one response: WTF why would you say that??

I dart back to the accusation, staring at it until it blurs. Finally, I refresh the post, hoping for clarity, for others to have piled on in defense of Morgan. But as I scroll, I can’t find it anymore. I check again—and again and again—but no matter how many times I refresh, it still isn’t there.

The comment is gone.

I shake my head, shake it off—just a sick joke, deleted as soon as the poster was scolded.

I swipe back to the picture and focus on Morgan’s face, partially obscured by the dumpling he’s holding. I zoom in, admire the pool-water blue of his eyes, the tortoiseshell frames of his glasses. I study the stubble along his cheeks, imagining the feel of it—a texture between velvet and Velcro—and notice a bit of ketchup in one corner of his lips. It’s small and round, like an errant drop of blood.

For a moment, I stop seeing the picture, see only the two of us together.

Morgan’s smile is red at the edge, and I lean in close, thumbing the color away.

Why We Love It

“I’ve been editing Megan Collins since her 2019 debut novel, The Winter Sister, but when she sent me the pitch for this new novel, I had goosebumps. This novel is Megan’s most ambitious novel, as well as her twistiest, walking a razor-thin line between infatuation and obsession to deliver major thrills. Megan has described Rosie, her protagonist, as a woman who thinks she’s living a rom-com, only to realize it’s a thriller—a kind of twisted You’ve Got Mail. And if you don’t trust me, read the first few chapters and you’ll be hooked!”

Raves and Reviews

“Part (possible) murder mystery, part deep dive into out-of-control social media addiction and part sleight-of-hand trick by the author ... terrific.”
The New York Times

“[S]pine-tingling… Collins expertly homes in on her characters’ complexities, nailing the way Rosie’s vulnerability gradually slips into obsession. With a pulse-pounding finale and plenty of exciting plot twists along the way, this is difficult to put down.”
Publishers Weekly

“Collins, who specializes in fiendishly clever psychological thrillers (including The Family Plot, 2021) outdoes herself here with a jaw-dropping premise that tightens into a deadly cat-and-mouse game… Collins keeps the suspense at cauldron-bubbling intensity throughout. A bravura performance.”
Booklist (starred review)

“Though absorbing and binge-able, this book is a triumph for more than just its entertainment value. Alongside the work of fellow authors such as Jacqueline Bublitz and Gillian Flynn, Collins’s fifth novel helps shape a new generation of thrillers that furthers the conversation about who gets to tell women’s stories and what kinds of women are deemed worthy of compassion.”
Bookstr

"Original, fast-paced, and with a twist in the middle that will leave your jaw on the floor, Cross My Heart deserves to be at the top of your must-read list!"
—Amy Engel, author of I Did It For You and The Roanoke Girls

"If Nora Ephron had written your favorite thriller, it would be Cross My Heart. Equal parts spine-tingling and soul-wrenching, Collins' latest unpacks the perils of parasocial relationships and the lies we tell ourselves with devilish wit, sizzling prose and a hair-raiser of a plot. The twists will have your jaw on the floor and your heart beating in time to Rosie's borrowed one. A true pulse-pounder with one question at its core: how far would you go to be with the one you (think you) love?"
—Leah Konen, author of The Last Room on the Left

“Part love story, part thriller, Cross My Heart is a sharply clever, highly entertaining, shifting kaleidoscope of a mystery.”
—Kimberly McCreight, New York Times bestselling author of Like Mother, Like Daughter

“With her fifth novel, Megan Collins proves once again why she should be on everyone’s must-read list! Cross Your Heart is the best type of psychological suspense–one that you want to immediately read again once you get to the last satisfying page. It has everything I love as a reader – an unreliable yet sympathetic narrator, cast of deliciously twisted people, razor sharp observations about relationships, and one twist after another. I read it in one night!”
—Kellye Garrett, award winning author of Missing White Woman

"Cross My Heart is a smart-as-a-whip thriller: electric, original, juicy, and full of clever twists and turns. Rosie Lachlan gives major Joe Goldberg vibes in the BEST way—an unhinged heroine fixated on love, with a big heart and an even bigger edge to her. Megan Collins is a master of suspense, with the ability to balance a page-turning plot with absolutely sparkling prose—I am in awe."
—Halley Sutton, USA Today bestselling author of The Hurricane Blonde

“When Rosie Lachlan's heart transplant leads her to her donor’s husband, a renowned crime fiction author, she thinks she’s finally found 'the one’…but will Rosie’s longing for true love blind her to the suspicious nature of his wife’s death? It’s rare to find a thriller that strikes a perfect balance between mystery and emotional complexity, but that’s the magic of Cross My Heart. Expect relentless tension, skillful misdirection, poet-worthy prose, and one of the best binge-reading sessions of your life. Megan Collins has outdone herself, and Cross My Heart is a triumph."

"Shocking, clever, and thoroughly enthralling. With its graceful prose and utterly jaw-dropping moments, this twisted yet heartfelt tale of deadly obsession is impossible to put down. A hypnotic stunner."
