A gripping, genre-bending novel about a mysterious new drug plaguing a small town and one girl who must uncover the terrifying truth behind the haunting side effects—or she will be next.

At sixteen Kyra is still haunted by the horrors she saw as little girl living with her mother’s drug addiction. Years later, Kyra doesn’t always feel like she belongs—and disturbing dreams come to her at night.

When a new party drug reaches her high school, Kyra’s life becomes an actual nightmare. A video challenge spreads among the students—and though she doesn’t participate, Kyra can’t escape the inexplicable side effects.

Everyone around her seems to be mysteriously changing, including the people she loves the most. Her brother has a new personality overnight. Her best friend suddenly feels like a stranger. The only other person who seems to notice the eeriness is Logan, the new boy at school. Like Kyra, he has steered clear of the party scene.

When the strangeness begins to feel sinister—or unnatural—Kyra is determined to find out exactly what is behind the mysterious drug. As she and Logan get closer to the truth, the line between Kyra’s past and present blurs . . . and she will need to face the terrors inside herself, or lose everyone she loves.
