At the Edge of the World — Avi

HE WAS A NAMELESS orphan, marked for death by his masters for an unknown
crime. Discovering his name -- Crispin -- only intensified the mystery. Then Crispin met Bear, who helped him learn the secret of his full identity. And in Bear -- the enormous, red-bearded juggler, sometime spy, and everyday philosopher -- Crispin also found a new father and a new world.

Now Crispin and Bear have set off to live their lives as free men. But they don't get far before their past catches up with them: Bear is being pursued by members of the secret brotherhood who believe that he is an informer. When Bear is badly wounded, it is up to Crispin to make decisions about their future -- where to go, whom to trust. Along the way they become entangled with an extraordinary range of people, each of whom affects Crispin and Bear's journey in unexpected ways. To find freedom and safety, they may have to travel to the edge of the world -- even if it means confronting death itself.
