Chloe McBride has some reservations about accepting her elderly great-aunts' invitation to spend part of the summer with them in Little Venice, but her initial reluctance is outweighed by her curiosity about the mysterious key that came with her aunts' note. She's also anxious to put the humiliating memory of a disastrous piano recital as far behind her as possible. Chloe's great-aunts tell her the legend of her great-grandfather, Dante Magnus, an ambitious magician who vanished without a trace almost a century earlier, and Chloe begins to search for clues to his disappearance. When her investigations eventually lead her to a mysterious rosewood box, which has been hidden for almost a hundred years, Chloe's belief in the power of magic forces her to confront her own fears and ambitions.
