Two sisters must rely on each other to escape a forbidden wilderness in this gripping survival story set in a utopian near-future.

No human has set foot in the Wildlands for twenty-five years . . . until today.

Welcome to the Wildlands—a vast rewilded project where formerly extinct animals roam free. Thirteen-year-old Astrid and her little sister, Indie, are traveling on a high-speed train through the heart of the preserve when, after an unexpected stop, they find themselves off the train, left behind, and all alone.

Stranded in a place of astonishing wild beauty and terrible dangers, they have only a backpack, a phone with no signal, and each other. Get lost in a world of forbidden natural wonders and pulse-pounding adventure as every wrong turn takes the sisters deeper into the wilderness in this gripping survival story.
