About The Book
An instant New York Times bestseller!
A “dazzling debut” (Booklist, starred review) middle grade fantasy about a girl caught between the realms of the living and the dead who gets lost in the Underworld—perfect for fans of Greenwild and Rick Riordan.
Senka lives between the realm of the Living and the realm of the Dead. As ward to Charon, the Ferryer of the Underworld, Senka assists in ferrying recently departed souls across the river and into their afterlife. Although Charon has taught her many Rules about life in the Underworld, there is much he avoids telling her. Though she doesn’t understand why the Rules are so important, she listens—she must heed them in order to become an official Ferryer, just like Charon.
Then a Living girl, Poppy, enters the Underworld to plead for help in finding the ghost of her brother. Poppy’s grief tugs at Senka’s heart—but helping Poppy goes against the very Rules Senka is so desperate to follow. When Poppy is yanked away by the river’s current, Senka leaps to save her, and she and Poppy are swept downriver, far from everything Senka has ever known.
Lost in the Underwild, Senka and Poppy encounter malevolent spirits of lore and eccentric ghosts—and not all are willing to let souls slip through their grasp. Senka knows the Living can’t stay in the realm of the Dead for long, and if Poppy isn’t returned home soon, she will risk becoming lost to the Underworld forever. But as Senka travels deeper into the Underwild, she discovers there are secrets her guardian has kept from her, including the mystery surrounding her own existence. As Poppy and Senka dodge angry demigods, hungry wraiths, and terrifying dragon chimera, Senka gets closer to learning the truth of her own past. Soon, Senka won’t just need to save Poppy’s life—she’ll also need to save her own.
Excerpt
CHAPTER ONE NIGHTMARES
THE RIVER IS THE COLOR of death. you’d think this wouldn’t be unusual for the Acheron—the long, wide river that flows through the Underworld—but you’d be wrong. The river that divides the Shore of the Living from the gates to the Under-After usually burbles in shades of silvery blue. Today its waters are too still; its mirrored surface colorless and cold as a ghost. I should know. I’m around ghosts all the time.
Now you’re probably wondering if I am a ghost. I most certainly am not. My fate is to walk amongst ghosts but to never become one myself. My name is Senka, and I am a Ferryer of souls.
That is, I will be a Ferryer soon. I’m the one and only assistant to Charon, the Ferryer of the Underworld. Well, I’m almost his assistant. Once he teaches me how to transport souls, I will definitely be his assistant. It’s the reason I’m here, after all. Every immortal in the Underworld serves a purpose; each of us is given a responsibility we’re committed to do for eternity.
Charon ferries souls. One day I will too.
I just need to convince him I’m ready to begin my training.
As the boat rocks beneath me, I tear my gaze from the motionless waters and shiver.
“Senka, are you cold?” A figure shrouded in a cloak the color of spilled ink dips his oar into the death-still river.
Don’t be alarmed by Charon’s appearance. Yes, he’s the immortal who ferries souls through the realm of the Dead and he seems scary, but he’s really a big nerd who likes drinking coffee, reading books, and playing board games on his days off. If you ignore the dark cloak and bone-pale hands and the lightning-blue gleam of his eyes, you’ll notice other features that aren’t so scary. Like the necklace I made out of hollowed-out bones painted in a rainbow of colors draped around his neck. Or the yeti-print T-shirt he’s wearing—a gift I ordered from the realm of the Living, with Mortimer’s help, of course.
Mortimer is our friendly neighborhood messenger-raven, the best mail service in the Underworld. Unfortunately, there aren’t many shops down here, unless you want something from Medusa’s Marvelous Menagerie (mostly snakes) or Nyx’s Shoppe of Nightmares (I have plenty of nightmares of my own, thank you). Everything Charon and I own either comes from catalogs Mortimer picks up for us in the realm of the Living or is gifted to us from the passengers Charon ferries through the realm of the Dead. Pro tip: If you want something without skulls on it, your chances are much better obtaining it from outside the borders of the Underworld.
“Take this. It will warm you up.” Charon pauses rowing and shrugs out of his long, hooded cloak.
I rub the goose bumps from my arms. “No, I’m okay.” The truth is, I’m afraid. Not of ghosts or the Underworld, obviously; it’s the weird stillness of the river. It has never been like this before. I know this sounds cliché, but it feels like a bad omen, like something wicked this way comes. I can’t let Charon know I’m skittish—no matter what happens, I’ll prove I’m ready to become a Ferryer, just like him.
I peer at him through my eyelashes. My guardian is tall and has biceps that make even Hercules jealous. (It’s true, Hercules said as much last time he dropped by for a visit.) I guess rowing a boat across the Acheron for thousands of years builds muscles. I frown at my own stick-thin arms and once again wonder why I fall epically short in the bicep department.
My origin story, as is the case with all denizens of the Underworld, is that I was created when someone was needed to do a job. Charon needed an assistant, and boom, here I was. Though why I sprang up as a scrawny twelve-year-old girl and not some buff, ancient dude like Charon is a bit baffling. Whenever I’ve asked Charon why this is, he dodges my question by commenting on the weather. Which, in case you’re curious, is always: Gloomy, with a chance of soup-thick fog.
As I get ready to state my case that today is indeed the day we should begin my training, he interrupts my mental preparations with a “Hmm.” The sound rumbles like thunder as he tugs his cloak back onto his shoulders.
“You seem quiet. Did you sleep okay?” he asks.
I fidget with the bracelet tied to my wrist. I’ve worn it ever since I can remember. The bracelet holds a single charm, a silver circle with a star stamped upon it. Charon claims it’s a charm of protection. I rub my thumb over the deep scratch running through its center.
Charon once said the charm would chase away nightmares, but so far it hasn’t worked—they still haunt me every night.
“When can we start my training?” I blurt, avoiding his question. “I’m ready to learn how to row the boat!”
Charon steers the boat back to our tiny island in the middle of the river, smack between the realm of the Living and the realm of the Dead. “Soon.”
I sigh. For immortals, “soon” could mean anywhere from one week to a hundred years. At this rate, it’ll take forever for me to become a Ferryer.
Oh, I should probably explain what this job entails. Ferryers are tasked to shuttle souls across the river that divides the two realms. Once across, passengers disembark into their Under-After, a location in the Underworld where newly arrived souls go to start their ghostly afterlife. Right now Charon is the only official Ferryer. He’s been at it a long time—for like an eternity. Whenever I ask if he’s old enough to be my grandpa or great-grandpa or great-GREAT-grandpa, he sighs, then tells me my tiny brain would break if I knew the real answer. I still ask, though. He’s the only person around here to talk to. Aside from the souls of the Dead, that is. But technically I’m not allowed to ask them questions. So he’ll have to deal.
This is Rule Number One for Ferryers: Avoid Questions from the Dead. And yes, when Charon repeats the Rule aloud, “Questions” is capitalized. Always.
There aren’t any passengers with us right now. It’s our tradition to hang out together once we complete our tasks for the day: Charon’s tasks being the Ferryer stuff (naturally), while my tasks include making my bed, cleaning up after breakfast, and trying not to fall asleep on my giant stack of home-schooling workbooks while Mortimer (who is also my teacher) squawks at me. On a normal afternoon, Charon and I play darts behind our cottage or pull out a board game if it’s too misty out, or we go to the Shore of the Living to skip rocks, which is what we decided to do today. And every night without fail I ask when I can become a Ferryer just like him.
He always answers, “Soon.”
And don’t think I’ve been sitting here, patiently waiting for that day to come. Secretly, I’ve been doing research and forming a plan. Okay, maybe not research in the standard sense of the word; there isn’t a Ferrying for Dimwits guidebook or anything. The “research” is stuff I’ve compiled on my own, taken from my observations on how Charon does his job, and includes the things I’ll need to master before becoming an official Ferryer.
These are:
Step One: Learn to row the boat.
Step Two: Get myself a fancy cloak like Charon’s.
Step Three: Ferry a soul to their Under-After.
Step Four: Collect payment for said ferrying job.
Step Five: Get Charon to admit I’m the best Ferryer ever and immediately promote me.
And if you’re thinking “Rowing a boat isn’t hard! You can learn without Charon’s help!” then you don’t know our boat at all. It’s one of a kind and it knows it. It is finicky, moody, a bit of a diva, and it won’t let just anyone hop on board and paddle around to their heart’s content. You have to have permission. Otherwise you could promptly end up under the boat rather than inside it.
And whose permission do you think it requires?
Charon’s, of course.
I can’t learn how to row the boat without his say-so (trust me, I’ve tried).
As of now, I’m on step one of my plan. Well, almost on step one. Let’s say I’m on step zero-point-five: Convince Charon to start my training already.
“Mortimer says you’ve made great progress in your Underworld history lessons,” Charon says, interrupting my internal plotting. “What’s your favorite thing you’ve learned so far?”
I fight the urge to roll my eyes. Mortimer’s been riding me to memorize historical events along with all the deities of the Underworld, including the ones currently locked up in Tartarus. Honestly, it’s not a subject I particularly enjoy. Every time I get events out of order or mix people up, he fixes me with his one eye (he wears an eye patch over the other), caws, and makes me start over.
I open my mouth, fishing for something to pull out of my long, painful lessons that could qualify as my “favorite” thing about Underworld history when the boat beneath me gives a mighty jolt.
“What was that?” I scan the river. Ripples slice across the water’s surface.
I gulp. Nothing has ever hit our boat before. Ever. There’s nothing in these waters to collide with it.
Slowly, I peer over the side. Something long and scaly streaks through the depths beneath us.
A scream tears from my lungs.
“Sit down!” Charon roars, gripping the oar and plunging it into the river.
He doesn’t have to tell me twice. I scramble from the edge and clutch the bench beneath me, my heart pounding. I can’t show Charon how scared I am. Ferryers are never scared.
But what I saw was impossible. It can’t be real. It can’t be here.
With an ear-splitting creak, our boat veers to the side, narrowly avoiding another collision as the scaled creature scrapes the hull. The wood groans, water lapping over the gunwale and drenching my boots. Silver scales erupt from the water as the creature leaps, then crashes back into the river. In that split second I spot a long snout, slitted eyes, and two horns protruding from its dragonlike skull.
Sweat breaks out across my skin—I’ve seen this creature before. Not in real life, but in my nightmares.
I struggle to breathe as countless other nightmare creatures emerge from the water. More swarm our boat, edging closer. Splinters from the bench pierce my palms, telling me I’m fully awake; my worst dreams have chased me here.
“There are so many!” I cry.
“Hang on!” As Charon’s powerful strokes steer us through the waters, the silver-scaled nightmares scatter.
The long, sleek body of the dragon slams against our boat. I scream as the world tilts. My hands scrabble at air as I’m hurled over the edge.

River of Spirits

About the Book
As the ward of Charon, the immortal Ferryer of souls, Senka has never known a life outside of the Underworld. Training with Charon as his assistant Ferryer, Senka knows that one day she will become an official Ferryer just like him. But when Charon unexpectedly leaves her alone, she goes in search of him and instead comes across a grief-stricken girl in search of her recently deceased brother.
Begrudgingly, Senka agrees to help this mortal girl, Poppy, but they accidentally get pulled into the Underwild, a part of the Underworld that Senka has been forbidden to enter. Together, Senka and Poppy confront the most dangerous immortals of the Underworld in their quest to find Poppy’s younger brother, Joey; what’s more, they must find him before Poppy loses her memories and mortality forever. As Senka and Poppy’s friendship grows, Senka begins to uncover clues that cause her to doubt everything Charon has told her about her life and how she came to be his ward. Can Senka help her new friend, and at the same time discover who she really is?
Discussion Questions
1. Senka notices a “weird stillness” to the river Acheron, and thinks, “It feels like a bad omen, like ‘something wicked this way comes.’” (Chapter one) What is an omen? How is what Senka believes to be an omen possibly her own intuition?
2. Nightmares plague Senka. In chapter two, after Senka falls into the river, the creatures that only live in her nightmares surround her. When Senka blurts out to Charon that these creatures are from her nightmares, she fears that he will feel betrayed. What is betrayal? Do you think Senka was betraying Charon by not telling him she was still visited by nightmares? Why or why not?
3. Hecate asks Senka if she’d like her to look into the future to gain “‘foresight of what’s to come.’” (Chapter four) What is foresight? If given the chance to see your future, would you want to look? Why or why not? What would be the possible positives, negatives, and consequences of knowing your future?
4. Shortly after Senka discovers the living girl Poppy, Senka experiences the girl’s intense grief: “Her grief pours out thick as fog, and I struggle for breath.” (Chapter eight) How can grief, or any extreme sadness, be like fog? Senka’s reaction to the girl’s sorrow makes something inside of her “crack.” Why do you think an immortal girl would have such a strong reaction to human grief? Why do you think Senka tries to avoid being around the grieving?
5. In chapter nine when Senka experiences a panic attack, Poppy helps her to regain calm by coaching her through a breathing exercise. How is this interaction an example of Poppy’s empathy? How does this act of care and kindness affect Senka?
6. Many of the characters in the story struggle with loneliness. What is the difference between being lonely and being alone? Thinking about Charon being alone for thousands of years before she arrived, and how Poppy has friends her age makes Senka realize how lonely she is. Discuss how having Poppy as a companion, even though she knows she should bring her back to the Shore of the Living, makes Senka feel less lonely.
7. Although she believes herself to be immortal, Senka responds in very human ways throughout the story. For example, when she and Poppy are trying to escape the carnival daimons, Poppy reaches out for Senka’s hand, and Senka experiences a “jolt, her skin a shock of warmth” and “a tingling feeling.” (Chapter thirteen) Discuss other ways in which Senka acts, thinks, and feels human.
8. A quest is defined as a “search or pursuit in order to find something.” (Oxford English Dictionary online resource). Poppy is on a quest to find her brother, Joey. After Senka begrudgingly helps Poppy, how does her journey through the Underwild also become a quest? What is she searching for? What does she discover along the way?
9. After Poppy asks Senka if she wants to talk about her feelings, Senka realizes “the thought of having a conversation with someone other than Charon and opening myself up makes me nervous, but also warm in my middle, like when I gulp down a mug of hot cocoa.” (Chapter twenty-one) Discuss this statement. What do you think she means by “warm in the middle”? How can she feel both feelings at the same time? Why is it important to talk about your feelings with people who care?
10. Senka is convinced that Charon is keeping secrets from her, lying to her about the Amulet of Cleaving and other important aspects of her life. How can secrets be threats to relationships? Do you think that Senka is making assumptions about Charon’s intentions? Why do you think that Senka felt “like maybe there’s a tiny bit of truth to Lionel’s words”? (Chapter twenty)
11. Charon is the only parental figure that Senka has ever known. Although she’s angry with him and doubts his sincerity, she thinks, “Maybe Charon is like a dad to me, after all.” (Chapter twenty-one) What are the qualities of a good parent? How does Charon exhibit these qualities? Do you think Senka would feel so betrayed if she didn’t consider herself part of Charon’s family? How do Charon’s words to Erebus in chapter twenty-three, “‘She is mine, as I am hers,’” contradict Senka’s doubt?
12. Poppy asks Senka a question she had never considered: “‘Do you want to be a Ferryer?’” Senka loves to paint, but the expectation for her eternal life is to be a Ferryer of the dead. She thinks, “Not once did I allow myself to dream about becoming something else.” (Chapter twenty-five) Why is it important to imagine what you could become? What do you want to become when you’re older?
13. Discuss how memory is woven throughout the story. How do Senka’s fragments of memories piece together to reveal the truth of who she is? How does fear keep her from her memories of how she came to the Underworld? When Senka hears the song “Stand by Me,” she has another nightmare. She considers that instead of a nightmare, it’s possibly a memory. How can music and memory be connected? Why do you think this song triggers such powerful images and emotions in Senka?
14. How is Poppy’s confession to Senka in chapter thirty-four a turning point in their relationship? How can honesty deepen a friendship?
15. While learning the story of Psyche and Eros, Senka realizes that Poppy based her quest for Joey on their story, but “instead of questioning what could go wrong if she attempted the same thing, Poppy had latched on to the things she wanted to believe.” (Chapter thirty-four) Explain what Senka means by wanting to believe. How did Poppy’s unwillingness to consider the danger cloud her judgment? How can wanting something so badly lead to poor decision-making?
16. Water is an important aspect of the story. Discuss the ways the author utilizes water for action, suspense, and symbolic meaning.
17. When Poppy and Joey are saying goodbye, Senka promises herself “to never let a day slip by unnoticed.” (Chapter forty-nine) What do you think she means by “unnoticed”? How can you be like Senka and make a point to experience or create something new every day?
Extension Activities
1. The Immortals. After reading River of Spirits, students will have been introduced to a variety of mythical immortals of the Underworld: Charon, Cyclops, Prometheus, and others. Have students choose one immortal from the story to research. As a culminating activity, students can create slide presentations to share with the class, or create an artwork that showcases aspects of their research.
2. C Is for Corvid. Mortimer the messenger raven and Mags the magpie are both corvids, birds that are part of the crow family, scientifically known as Corvidae. Corvids are known for their keen intelligence and social behavior. Work with the school’s science teacher to learn about this fascinating family of clever birds. Visit PBS online to learn more about corvids and to view a selection of short videos: https://www.pbs.org/wnet/nature/group/birds/crow/.
3. “Stand by Me.” The song “Stand by Me” helps Senka unlock her memories of her father and her life before entering the Underworld. Print copies of the song lyrics for each student to read. Discuss how the lyrics relate to the story. After the discussion, play the recording by Ben E. King to the class.
4. Memory Lane. Senka paints pictures of boats over and over again and comes to realize that the image is connected to an experience she had with her father. Have students think about a favorite family memory. Spend time working with students as they write a one-page reflection of the memory. After the writing process is complete, students can make an illustration of a key detail of their memory.
5. Chimera Cha-Cha. Poppy describes chimera as “creatures that have all different animal parts.” (Chapter seventeen) What Poppy is describing is a hybrid creature, one that is composed of many animals. Give students an opportunity to conjure up a chimera of their very own, composing the creature with at least three distinct aspects of at least three animals. Provide drawing paper, crayons, markers, and colored pencils so students bring their chimera to life.
