A beguiling fantasy about the vacation of a lifetime. Hannah, Zachary, and Sarah Emily are spending the summer at their Great Aunt Mehitabel's house on faraway Lonely Island. There, in a cave hidden high above the ocean, they discover a fabulous creature: a glittering three-headed dragon with a kind heart, an unpredictable temper, and a memory that spans 20,000 years. Transported by the magic of the dragon's stories, the children meet Mei-lan, a young girl in ancient China who is called upon to save her village from great danger. They sail the seas in a 19-century ship with cabin boy Jamie Prichett. And, in more recent times, with Hitty and her brother Will, they survive a frightening plane crash on a desert island. In a novel as mysterious and spellbinding as the dragon's stories, Rebecca Rupp explore what three children from the present learn from the pastand from an unlikely, but wise and generous friend.
