A magician sends a melancholic maiden on a rescue mission in Hell in this humorous fantasy adventure by a New York Times–bestselling author.

As one of the trouble-making twins of Castle Zombie, Lacuna used to have so much fun when she was a little girl. But now at thirty-four, she's bored stiff and wonders where her life went horribly wrong. To escape her funk, she heads to Good Magician Grey to pose a question. Of course, in Xanth, getting an answer is far from simple . . .

Grey sends Lacuna to Hell in a handbasket . . . literally. There, she meets Good Magician Humfrey, who's spent the last ten years waiting to get his wife back from a terrible demon. With her magical talents—and a few gorgons—Lacuna just might be able to help Humfrey, escape Hell alive, and fix her boring life, once and for all.
