Black Mirror meets Goosebumps in the first installment of this fast-paced middle-grade horror series by New York Times-bestselling authors Erin Entrada Kelly and Eliot Schrefer featuring tales of technology gone wrong. Eleven-year-old Sofia Mendoza is a gamer, not a camper. She should be at home building landscapes and fighting monsters in Sandbox, not deep in the forest with five other kids, who might as well be playing her favorite game in tutorial mode. Even worse, there's something off about this summer camp. There are creepy, mechanical vultures, cloaked NPC figures, and the only adult is Monarch, a grim woman in combat boots. And then the game of elimination begins. Sofia may be caught in the clutches of Camp Forestjaw, but she'll do anything to survive. Anything. The problem is, in Forestjaw, everything you've ever done--no matter how long ago--comes back to you . . .
