Determined to seek his fortune, Percival Taylor leaves behind his sleepy hometown and sets out to become a legendary pirate-- if only anyone would allow him anywhere near a ship! He means to win the heart of the beautiful Tuppence Magrathia Paddock, who has mistaken him for a pirate rogue out of one of her romantic books. Percival eventually finds himself captain of a broken-down ship, complete with a crew of reluctant pirates, a jilted fiancée, a reclusive master shipwright, and an old professor with a magical secret that could kill them all.
