After a plane crash, thirteen-year-old Brian spends fifty-four days in the Canadian wilderness, learning to survive with only the aid of a hatchet given him by his mother, and learning also to survive his parents' divorce.

Six kids. One shipwreck. One deserted island. After their ship sinks, Luke, Ian, JJ, Sharla, Will, and Lyssa must find a way to survive. They have no food and very few supplies. They think they're all alone, but they're not. And that's even worse.

Sailing with their parents and their sister Candace, Phineas and Ferb, along with their friend Isabella, are stranded on a deserted island until the parents repair the boat.

Graystripe and his friend, Mille, are finally on their way. Finding the ThunderClan is a lot harder than they'd imagined, though.
