The first book in an action-packed fantasy adventure series featuring witches, shape-shifters, and other creatures of fairytale and folklore, including two brothers—one human and one a goblin changeling—on a lifechanging quest into the Oddmire. Magic is fading from the Wild Wood. To renew it, goblins must perform an ancient ritual involving the rarest of their kind—a newborn changeling. But when the fateful night arrives to trade a human baby for a goblin one, something goes terribly wrong. After laying the changeling in a human infant’s crib, the goblin Kull is briefly distracted from his task. By the time he turns back, the changeling has already perfectly mimicked the human child! Too perfectly: Kull cannot tell them apart. Not knowing which to bring back, he leaves both babies behind.
