About The Book
Perfect for fans of How to Survive Your Murder and Dead Girls Can’t Tell Secrets, this young adult thriller unspools the truth behind a tragic murder through multiple unreliable narrators who all have secrets to keep.
Here’s what we do know: there was a party at Trevor’s house last night, and things went horribly wrong. By the end of the night, there were two dead bodies in an upstairs bedroom: seventeen-year-old Sadie Cooper and her killer, Mason McDonald. The murder was heartbreakingly witnessed by Sadie’s twin sister, Jayne, and Sadie died in her arms. Mason was killed by Sadie’s boyfriend, Ben, in an attempt to save Sadie.
Aside from figuring out Mason’s motive, it should be an open and shut case.
But it’s not.
The story unfolds just after the murders, and Jayne, Ben, and Sadie’s best friend, Liz, are telling the cops what transpired at the party and the events leading up to it. But little details don’t match. And those little details start to add up to big discrepancies. But who’s lying, and why?
The shocking truth is revealed in the third act, when the POV shifts to victim Sadie herself, in the days leading up to the party. Witness exactly what happened—and see if you can piece it all together. Because poor Sadie totally missed what was right in front of her.
