A mythic muse descends Parnassus for a perilous quest in the world of Xanth in the New York Times–bestselling author's raucous fantasy series.

When Clio, the Muse of History, discovers a bewildering discrepancy in her Chronicles of Xanth, she leaves her comfortable study on Mount Parnassus in search of answers. But it won't be as easy as asking her old friend, the Good Magician Humphrey, to look it up in his Book of Answers.

Instead, Clio must brave a dangerous Dragon World and search for the fabled Currant, a rare red berry which holds the secret she's after. Along the way, Clio meets the brave and beautiful Becka Dragongirl, a couple of pocket dragons, a little girl whose destiny collides with hers, and Sherlock, an unassuming man from Mundania who might just be a master magician—and the unlikely man of Clio's dreams . . .
