From the author of Edgar Award finalist Grit and The Lies They Tell comes a tense, atmospheric novel for fans of E. Lockhart and Marieke Nijkamp, about friendship, truth, and the creeping fears that can’t be outrun.

Whenever another kid goes missing in October, the kids in the old factory town of Pender know what is really behind it: a monster out in the marshes that they call the Mumbler.

That’s what Clara’s new crew tells her when she moves to town. Bree and Sage, who take her under their wing. Spirited Trace, who has taken the lead on this year’s Halloween prank war. And magnetic Kincaid, whose devil-may-care attitude and air of mystery are impossible for Clara to resist.

Clara doesn’t actually believe in the Mumbler—not like Kinkaid does. But as Halloween gets closer and tensions build in the town, it’s hard to shake the feeling that there really is something dark and dangerous in Pender. Lurking in the shadows. Waiting to bring the stories to life.  

• New Girl in Town: Clara Morrison just wants to fit in, but in a town like Pender, being new makes you a target—for pranksters and for something much older.
• The Mysterious Believer: She’s not sure she can trust the magnetic Kincaid, the one person who truly believes in the Mumbler. But she also can’t seem to stay away from him.
• Found Family: Navigating intense new friendships with her crew, Bree and Sage, means Clara finally has something to lose when the shadows start to close in.
• Atmospheric Suspense: Set against the backdrop of a decaying factory town and an escalating Halloween prank war, this tense mystery will keep you guessing until the final page.

“Bowstring-taut tension builds gracefully through the novel.... The book’s strength, however, is offering readers plenty of authentically developed characters with whom they can identify, from teen pranksters to hardworking parents.”
