Lacuna, twin sister of Hiatus, seeks a cure for terminal boredom for the good magician. She finds him in the waiting room of Hell, having waited ten years for appointment, and helps him rescue his wife from the demons there. Other books by Piers Anthony include "Isle of View" and "Phaze Doubt".
Youth is Wasted on the Young
Being grown up is a drag . . . or so thinks Lacuna, one of the michievous Castle Zombie twins. So she makes the Good Magician Grey an an offer he can't refuse. Thirsty for a taste of the Elixir of Youth, she'll help him outwit the evil Com-Pewter if he'll send her to Hell (in a handbasket, no less) to find Humphrey, the missing sorcerer. And while there, she'll learn the True History of Xanth (simplified) and help rescue a blushing Rose from the demon X(A/N) . . . with the help of a gorgon or two.
