“A desert full of mystery. A girl who sees things she shouldn’t. Desperate to unlock the secrets of Twentynine Palms, I raced through this book!” —Erin A. Craig, New York Times bestselling author of House of Salt and Sorrows For fans of Stranger Things and Veronica Mars comes a new YA mystery about a girl whose desperate search for her missing friend unearths dark secrets, preternatural threats, and a truth that could ultimately tear her family, friends, and town apart. Welcome to Twentynine Palms, where nothing is what it seems. Rylie hasn't been back to the military base in Twentynine Palms since her father died. She left a lot of memories out there, buried in the sand of the Mojave Desert. Memories about her dad, her old friends Nathan and Lily, and most of all, her enigmatic grandfather, a man who cut ties with Rylie’s family before he passed away. But her mom’s new work assignment has sent their family to Twentynine Palms again, and now, Rylie’s in the one place she never wanted to return to. At least her old friends are happy to welcome her home. Well, some of them, anyway. It turns out Lily is gone, vanished into the desert. To make matters worse, there are whispers around town of a mysterious killer on the loose. But it isn’t just Twentynine Palms that feels frightening—there’s something wrong with Rylie, too. She’s seeing things she can’t explain. Visions of monstrous creatures that stalk the night. Somehow, it all seems to be tied to her grandfather and the family cabin he left behind. Rylie wants the truth, but she doesn’t know if she can trust herself. Are the monsters in her head really out there? Or could it be that the deadliest thing in the desert . . . is Rylie herself?
