Koipaw and his sister, Apricotpaw, are the newest apprentices in LeafClan, one of the three Clans in the east. They live normal lives, striving to be the best warrior and medicine cat they can be, but a shadowy monster haunting Koipaw's dreams threatens to tear apart not only LeafClan, but the other Clans as well. A tale separate from the canon books, this work tells the story of LeafClan, MountainClan, and MarshClan, Clans living on coastal Asia.
