Witch’s Stone, by Jamaila Brinkley

Duncan Lowell’s explosive magic is fueled by an equally explosive temper. He’s stayed away from the earldom he rules from afar to escape memories of his vicious father. But when he must return, other memories surface, too – of his childhood friend and conspirator, Fiona: the future Witch of Kilgoran.

Fiona Fanshawe has dedicated her life to the people of Kilgoran. After tragedy marred her family, she’s vowed to stay aloof, serve the village, and never marry. When Duncan arrives, demanding that she retrieve the Stone that caused her family so much pain, she’s forced to re-evaluate all of her choices.

Duncan’s demons make him fear hurting those he loves; Fiona’s make her terrified of getting hurt. Now, the witch and the earl will have to decide whether they will be more dangerous together – or apart.
