Under Your Spell by Shiloh Walker

You will never love another.
Aislinn was the only woman Nicholas Montgomery would ever love, a fact he knew even as he was pledged to marry another.
The young, powerful witch’s heartbreak and fury led her to cast a spell that trapped them both for hundreds of years…
You will never love another like you love me.
You will never know a moment’s peace for what you have done.
Until you love me enough to forsake everything – your honor, your pride, your own soul, we cannot be together.
After more lifetimes than he wants to consider, he’s been reborb as Sean Concannon, a powerful witch, and he has finally found her, his Aislinn. But to claim her, he’ll have to make a choice, and a sacrifice he’d never prepared for.
