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 . . .
