Swell Foop

The enchanted land of Xanth faces a matter of intense gravity when gravity itself disappears in this harrowing and hilarious fantasy adventure.

Cynthia Centaur has come to the Good Magician Humphrey at exactly the wrong time. Seeking an answer to a rather personal question, she expects only to face the typical challenges. Instead, she is charged with saving all of Xanth from a terrifying threat.


The powerful Demon Earth has been kidnapped. And when he disappears, the world's gravitational field goes with him. The very fabric of Earth—and, incidentally, Xanth—will soon unravel unless Cynthia and her companions can find a mysterious object known as the Swell Foop and use it to defeat a terrifying enemy in a comic contest.


The twenty-fifth volume in Piers Anthony's legendary Xanth series, Swell Foop blends humor and danger, romance and wonder, in one of his most intricate and intriguing tales yet.
