My Side of the Mountain Trilogy (My Side of the Mountain, Vols. 1-3)

This is a terrific trilogy by multiple Newberry winner Jean Craighead George. In these novels, Sam Gribley is tired of living in a crowede New York City apartment, so he runs away to the Catskill Mountain wilderness to forge a life of his own. With only a penknife, a ball of cord, an ax, $40, and some flint and steel, he must rely on his ingenuity and on the resources of the land to survive.
