The Keeper

Oisin is not sure he wants to be Keeper of the Book of Magic - but when his little sister Sorcha is kidnapped by the Morrigan, a raven-goddess with a heart as dark as her feathers, he has to learn how to use the Book for good. On his quest to rescue Sorcha, Oisin must conquer the Mountain of Wind, defeat snow-snakes and shadow fish and enter the Morrigan's chamber of bone. Can Oisin discover the secret of the Book, so that he can truly become its Keeper and release Sorcha from the grasp of the Morrigan?
