for Merlin by Jane Yolen
In flight from the magic visions that plague him, Merlin falls into the hands of the wodewose--wild folk who, according to legend, live in the company of wolves and devour children. But far from being wild, the wodewose are an enormous family of the unwanted, the abandoned, and the homeless. For once Merlin has found a place where an orphan like himself belongs. The triumphant conclusion to the Young Merlin Trilogy.
