Bewitched Souls (The Coven #1‪)‬

The Coven is a special group of witches given charge of the manor on Genum Island, and Talis is considered the head and strongest of it. Joined by his sister, Teryn, and her husband, Cian, they protect their magic based home from the forces of darkness who seek the mysterious power of their home. It's all routine, until Talis' old crush shows up with a strong desire to take the head witch for himself.
Dion has come to terms with what he wants, and that's Talis. He has a lot to make up for, but with him comes trouble. Hot on his tail is his ex-girlfriend, and with her is a demon who has a craving for souls and a rise to her former glory.
The Coven has no choice but to stand against the greatest threat they've ever faced. How far will they go to save a soul?
