The rest of the camp is wiped out in a moment--leaving Josh, Derrick, Brooke, and Shannon alone, hundreds of miles from the nearest town, with meager supplies, surrounded by dangerous Alaskan wildlife.

Josh and his fellow campers face a struggle for survival in their hike back home--to an America they might not recognize"--Dust jacket.
