Toby has to finish the final thing on The List.

It's a list of brave, daring, totally awesome things that he and his best friend, Lucas, planned to do together, and the only item left is to hike the Appalachian Trail. But now Lucas isn't there to do it with him.

Toby's determined to hike the trail alone and fulfill their pact, which means dealing with little things -- the blisters, the heat, the hunger -- and the big things -- the bears, the loneliness, and the memories.

When a storm comes, Toby finds himself tangled up in someone else's mess: Two boys desperately need his help. But does Toby have any help to give?

The Trail is a remarkable story of physical survival and true friendship, about a boy who's determined to forge his own path -- and to survive.
