Dragonbound — Carl Miller

To love a wizard is dangerous. To bond with a dragon means death.... Periwinkle was a warrior, born and bred to the sword. Bellchime was a wizard, who made his way as a wandering bard. When she was but a child, Periwinkle promised her heart to Bellchime. But four long years passed, and he never returned to claim her. Then she dreamed: of Bellchime, amidst a goblin-haunted wilderness, his mind and spirit in thrall to a fearsome dragon...

DragonBound! Hunted by ordinary men, doomed to become less than human, lost forever to love and light. She would not let this be! Periwinkle vowed to free Bellchime from the terrible creature -- though she herself might become dragonbound.
