Passager: the young Merlin trilogy, book one

A boy is abandoned in the woods of medieval England. A year passes--a year of terror and hunger, of sleeping in trees and foraging for food, of outrunning packs of wild dogs--until one day a falconer captures and tames the boy as he would any passager, a young bird caught in the wild and trained. The falconer adopts the boy and teaches him all of the things he’s forgotten, including the boy’s true name--and the legacy of magic that will be his when he comes of age. “This first book of the Young Merlin Trilogy will have readers awaiting the sequels.”--The Horn Book
