Determined Billionaire by Sierra Cartwright

Determined to marry Sinead O’Malley and end their centuries-old feud, Jack Quinn chases the fierce and evasive woman across two continents.
When the gorgeous billionaire catches up to her, Sinead refuses to go down without a fight. No matter how tempting he is, she will not play house with her sworn enemy.
But the Quinn men have been kidnapping O’Malley women for almost a millennia, and now Jack understands why. She’s as proud as she is stubborn, and she demands the one thing he can’t give—his heart.

Will Jack learn that she is worth any cost, or will he lose her forever?
