Daniel Redmayne is fast asleep on the first night of a whitewater rafting camping trip, when he's awoken by screams. The dam has failed. The river is surging, and their camp will be underwater in a matter of moments.

As the shrieking roar of the river rushes closer, the kids scramble to higher ground. They make it; their counselors do not.

Now they're on their own, with barely any supplies, in the middle of the Montana wilderness. Do Daniel and his four classmates have what it takes to stay alive until they can get rescued? Alone in the wild, they forge powerful bonds -- but develop dangerous disagreements. If nature doesn't break them, they might just destroy each other.

This gripping survival story from the Newbery Honor author of Wildfire is filled with adrenaline-pumping adventure and moments of true bravery.
