'Paige loves stories about myths and monsters but she never thought she’d become part of one. When Paige’s crazy Welsh aunt sends her the last in a series of ancient talismans for her fifteenth birthday gift, her whole world turns upside-down. Cam, the new boy in school has mystical secrets too and when he sees Paige’s birthday gifts he realizes his grandfather’s warnings weren’t nonsense, after all. Danger looms in the form of Balor and his band of sea monsters. Along with friends Tegan and Jacko, Paige and Cam must learn how to wield their mysterious powers if they are to protect their treasures, their families and maybe even the world.'
