In the Line of Duty — Donna Alward

Ex-soldier Jake Symonds has been a thorn in Constable Kendra Givens's side since the night they first met, when she had to throw him in a cell. Two years later, she's called to a break-and-enter at his pub and is surprised by the now-competent businessman offering to cook her breakfast. Their emotional baggage might be stacked too high to risk anything deeper-but Kendra soon realizes the greatest danger Jake presents is to her heart.
