Ethan Chase has been plagued by the fey all his life. Protective of his family and resentful of his older sister, the Iron Queen, whom he believes deserted them, Ethan wants only to be left alone. But that becomes impossible when exiled fey start dying or disappearing. When Ethan is attacked, he begins his own journey through the dangerous world of the fey, joined by a girl he will give his life to protect and a reluctant ally who might just be his nephew. Soon they learn of the rise of an ancient type of faery that threatens the balance of the Nevernever and the human world — the Forgotten.
