When a magician’s son disappears, a madcap mystery sets off a parallel pair of perilous quests in this beloved fantasy adventure series.

The Good Magician Humfrey’s son Hugo has vanished from his cellar. And what’s worse, there’s a murdered man left in his place. With Humphrey’s book of answers scrambled, it’s a mystery that can only be solved by . . . a thirteen-year-old girl named Debra.

Hailing from Mundania, Debra was hoping to lift an obnoxious curse on her name. But thanks to the strange ways of Xanth—and Hugo’s gorgon mother—she is now a flying centaur embarking on an incredible misadventure through astonishing locales that reach back to the origins of time itself.
