NATIONAL BESTSELLER • In this nail-biting thriller, a horror-themed birthday party turns deadly when guests start disappearing—and the birthday girl realizes that she must face a long-buried secret to make it out alive.

“Buckle up. This clever, sinister, atmospheric thriller had me staying up all night.”—Natalie Barelli, bestselling author of Finders Keepers

Tippi is ready for a fresh start. After breaking off her engagement to an increasingly demanding, controlling, and emotionally unstable man, she is newly inspired to do whatever it takes to put herself first. Plus, her thirty-fifth birthday is coming up: a perfect occasion to ring in this new era. Tippi’s friends see the opportunity, too, and lean into her love of horror films by throwing her a lavish theme party at a secluded mansion, where everyone dresses as characters from iconic scary movies. But Tippi's attempts to enjoy the night are shattered when she starts receiving terrifying messages from her ex, Oliver, to expose a secret she was ready to take to the grave.

At first, Tippi can’t believe her eyes. Oliver moved across the country after they broke up—he can’t have crashed her party. Could one of her friends have found out? But when her guests begin to disappear one by one, it becomes clear that the threats have very real consequences. And the messages make clear one thing: the call is coming from inside the house.

As Tippi is forced to navigate the deception of those closest to her, she realizes that in the end, some things are indeed like in the movies, and she’ll do whatever it takes to just survive the night.
