The Dastard
Piers Anthony
 Becka was a crossbreed - the daughter of Draco Dragon and a lovely human woman who met, by chance, at a Love Spring. Now fourteen, Becka was beginning to wonder where in Xanth she belonged, on the ground with her mother's people or flying the skies with her father's kind. So she journeyed to the Good Magician Humfrey to discover her true purpose in life. Much to her astonishment and surprise, the Magician told her that a great Destiny awaited her, one that would affect the future of all of Xanth. To unravel the mystery of her Fate, Becka did as Humfrey bade her: traveling on foot to the statue of the dreaded Sea Hag to meet the man who would be waiting for her there, and offering him her assistance. But to her dismay, Becka discovered that the one who awaited her there was a dangerous, despicable libertine who called himself the Dastard. Once a common country boy, the Dastard had sold his soul to a detestable demon in exchange for the power to erase events and rewrite history to suit his own devious ends. Lacking a conscience and filled with craven self-loathing, he roamed the width and breadth of Xanth in search of anyone happier than he was. Once he found them, he used his malevolent talent to "unhappen" their happiness so that others could share in his misery. Determined to honor her vow but despairing of her ability to help this man and still preserve her virtue, Becka set out on a wide and perilous journey that led from the mists on Xanth's distant past to the tiny planetoid of Ptero, where everyone in Xanth who might have been actually existed. There she discovered a magic that was far stronger than the Dastard's: the awesome power of the human heart.
