The Mage's Heart - Love and Other Sorcery, #1

Don't stray from the path.When Siorin encounters a mysterious black-haired mage in the forest on her way to the local good-witch, she knows better than to stray from the path. Doing so would be inviting trouble from the fairy brethren with whom mankind shares their world. His plight, however, moves her, and she rescues him despite misgivings. Rivyn has cast a destiny spell which he believes brought him Siorin, so he doesn't hesitate to steal her, well and truly taking her off her path when he does so.
The mage irresistibly draws and seduces Siorin as he leads her on a quest to rebuild his power so that he can return to the Fae Court and reclaim what has been stolen from him. But what Rivyn has lost is not what he needs to seek. Will Rivyn choose his power, or his heart?
