Dragon's Heart — Marly Mathews

A relationship between a dragon shifter and a wizard was unheard of -- and certainly frowned upon. Yet, Grania found William nearly irresistible, feared, knew, if he ever touched her she'd never be able to control the mating fire.
With Dragonia torn by Civil War and the rebels winning the fight, it was only a matter of time before the dragon shifters focused on Earth in their determination to take back what mankind had taken from them centuries before. The wizard William Lightfoot was their only hope, the only one capable of conjuring the spell they needed to defeat the rebels, and it was Grania's duty to defend him at whatever cost.
She hadn't suspected what it would cost her, though, would never have believed she would find her soul mate to be a wizard, not one of her kind.
