Devil's Own — Temple Hogan

Orphaned when her father is burned at the stake as a witch, Edra Corwin is now the ward of her aunt and uncle who are narrow-minded and superstitious. Having grown up in a house of learning and intellectual stimulation, Edra struggles to tame the special powers she knows she possesses, but can't show for fear of retribution. Her life seems pretty dismal until wealthy Maximillian Payne, an old friend of her father's, returns to rescue her.

Maximillian didn't realize the girl he returned to take charge of has become a beautiful young woman, who possesses the same gifts that cost her father his life. He knows he must teach her how to protect herself, while honing her skills. He just doesn't plan on falling in love with her, but what can a man do against a green-eyed witch who teaches him a few things as well?
