Seventeen-year-old Ryan Poitier Sharpe is a gutsy, outgoing girl who spends her summer days hurling herself out of planes at her parents’ skydiving center in the Mojave Desert. Fiercely independent and willing to take risks, she challenges those around her to live life fully. But after a brush with death, Ryan is severely altered—she’s not the same thrill-seeking girl she once was and seems to be teetering on the edge of psychosis. As her relationships crumble and her life unravels, Ryan must fight the girl she’s become—or lose herself forever—in this eerie and atmospheric thriller.

"Readers will be easily swept along in this fast-paced thriller, unsure whether Ryan’s narration will reveal that she is supernaturally possessed or insane." —Booklist
