The horror is closer than you think.

It's been almost a year since Makani Young came to live with her grandmother in landlocked Nebraska, and she's still adjusting to her new life. And still haunted by her past in Hawaii.

Then, one-by-one, the students of Osborne High begin to die in a series of gruesome murders, each with increasing and grotesque flair. As the terror grows closer and the hunt intensifies for the killer, Makani will be forced to confront her own dark secrets.
Stephanie Perkins, bestselling author of Anna and the French Kiss, returns with a fresh take on the classic teen slasher story that’s fun, quick-witted, and completely impossible to put down.

Published by Dutton in 2017.

"Teen romance and grisly murders crawl into the backseat of the car for a make-out session."


"Perkins deftly builds the suspense like a pro: an uneasy opening leads to some legitimately horrifying murders, and the identity of the killer isn’t quite as important as the motivation . . . Readers will be sleeping with one eye open."


"There's Someone Inside Your House is a heart-pounding page-turner with an outstanding cast of characters, a deliciously creepy setting, and an absolutely merciless body count. Best read at night with a big bowl of popcorn, this is a killer addition to the slasher genre written by one of the best contemporary YA writers around."

—COURTNEY SUMMERS, author of All the Rage and the This is Not a Test series

"There's Someone Inside Your House is equal parts heart-stopping horror and steamy romance. It's tons of bloody fun."


"The best new horror of the season. . . . Fans of the genre will feel at home with this book, which mixes the wit of modern slasher films like Scream and I Know What You Did Last Summer with the grounded characters and emotions of contemporary YA."


"Perkins lulls readers into a false sense of security before twisting the knife . . . the body count keeps rising, leaving readers with questions of motive and where it will all end."


"Turn on—all—the lights before reading this hair-raiser full of serious Scream vibes."
