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. Tinn and Cole are raised as human twins, neither knowing what secrets may be buried deep inside one of them. Then when they are twelve years old, a mysterious message arrives, calling the brothers to be heroes and protectors of magic. The boys must leave behind their sleepy town of Endsborough and risk their lives in the Wild Wood, crossing the perilous Oddmire swamp and journeying through the Deep Dark to reach the goblin horde and discover who they truly are.

Human and goblin brothers Cole and Tinn are finding their way back to normal after their journey to the heart of the Oddmire. Normal, unfortunately, wants nothing to do with them. Fable, the daughter of the Queen of the Deep Dark, has her first true friends in the brothers. The Queen allows Fable to visit Tinn and Cole as long as she promises to stay quiet and out of sight—concealing herself and her magic from the townspeople of Endsborough. But when the trio discovers that humans are destroying the Wild Wood and the lives of its creatures for their own dark purposes, Fable cannot stay quiet. As the unspoken truce between the people of Endsborough and the inhabitants of the Wild Wood crumbles, violence escalates, threatening war and bringing Fable’s mother closer to the fulfillment of a deadly prophecy that could leave Fable a most Unready Queen.

The third adventure in the beloved fantasy series full of folklore and mayhem, from the creator of Jackaby . Brothers Cole and Tinn are determined to solve a mystery almost as old as they are: What happened to their long-missing father? Joseph Burton vanished without a trace, leaving the babies’ mother to raise them—one human, one a goblin changeling—alone. Some say Joseph abandoned his family, others that he met foul play looking for a way to get rid of the changeling imposter. Cole is determined to learn his father’s true fate, so he and Tinn set out on a dangerous quest to the deepest, most deadly limits of the Oddmire—with the help of Evie, expert on the creatures of the Wild Wood, and Fable, the indomitable half human, half fairy. Meanwhile a shudder runs through the forest. Increasingly powerful earthquakes shake the land, sinkholes form, and the spriggans, trolls, and other creatures along their path speak of an ancient evil on the rise . . . In the third book of the Oddmire series, New York Times bestselling author William Ritter takes readers on an unforgettable journey of family, fate, and a dangerous, magical forest.
