Knight's Redemption by Katie Reus

They met while he was undercover…

While working undercover, Cormac Knight fell for the wrong woman. Then he was forced to leave without a word in the middle of the night to keep them both safe. Even though he hasn’t contacted her since, she still haunts his dreams. When fate gives him a second chance, he’s determined to make things right—even if that means she starts a new life without him.

Then he left her behind…

Daniela has never forgiven Cormac for leaving the way he did. But she’s got problems of her own. She’s been trying to make a clean break from her criminal family for years, and now time is running out. When he suddenly appears out of nowhere and offers to help her, she cautiously takes the lifeline. Unfortunately the chemistry between them is still off the charts. And if they’re not careful, that connection could get them—and everyone they love—killed.
