The Misadventures of Ka-Ron the Knight: The "Nown" World Chronicles, Book One (Unabridged‪)‬

A brave knight is wrongfully cursed, turning him into the most beautiful woman on the planet. To reverse this spell, "she" must form a quest to seek out the Wicca master who cast the spell, hopefully changing her mind. 

Along the way, the knight falls in love with her squire, battles vampires, helps aid an elf revolution, and even becomes pregnant. Ultimately, her squire must make the hard choice: Does he help his master complete "her" quest, or does he try to keep his one true love?
