Hatchet meets Survivor in this high-action, humor-filled middle grade adventure about two kids stranded in the wilderness, whose annoyance with each other rivals the roaring rapids and ferocious predators they must face.

12-year-old Sadie Hahn didn’t plan to eat grubs on camera to win a contest. And she definitely didn’t plan to win first prize—a guest appearance on a Youtube show hosted by America’s favorite 13-year-old survivalist Radley Shaw. But she’ll do anything to cheer up her little brother Silas, who’s too young to qualify.

Rad has millions of followers and exactly zero real-life friends, so the contest is a great chance for him to hang out with kids his own age. But it’s hate-at-first-sight when Silas throws a wrench in his plan and Sadie decides Rad is just a clueless poser who doesn’t know the first thing about survival.

Disaster strikes when their scripted rafting trip turns into a real fight for survival. Lost in the mountains, Rad and Sadie must find shelter, build a fire, forage for food and try not to become food for a hungry predator. But can they stop bickering long enough to hack it in the wilderness? And will that be enough to keep them alive?
