On the Edge by Brittney Sahin

From a horse farm in Kentucky to Dublin, Ireland – falling for her hot Irish boss is not part of the plan. Billionaire businessman by day, fighter by night . . .

Anna is relieved to leave her small hometown behind and get a fresh start with an internship in Dublin. What she doesn’t expect is to bump into a strange man in her new apartment on her first night there. A man who, it turns out, also owns the company she’s joined.
As Adam and Anna are thrust together more and more, she discovers he’s a man with secrets and a dark past – a past that seems to be reaching for her.
Although Anna can sense how dangerous Adam is, she can’t seem to resist him. And while he fights his feelings, longing to keep Anna safe, neither of them can see that their only hope for survival is each other.
