Crossing the Line by Jessica Prince

Some lines are meant to be crossed.

Trent Montgomery knew all about loyalty and responsibility. Tracking down his friend’s long-lost sister and making sure she was safe was just another job, a favor from someone he cared about. He wasn’t supposed to get attached. But when he started to fall for the woman who had been hiding from the world, things got a lot more complicated than he ever expected.
Cheyanne Knightly knew all about living in fear. The life she’d made for her and her daughter was as stable as a house of cards. One stiff breeze could send her whole world crumbling. But when a new guy blew into her small town, stirring up Whitecap’s rumor mill, she found herself drawn to him in a way she never expected.
Lies were told. Secrets were uncovered. Lines were crossed. When the truth finally came out, Trent had to find a way to protect the woman who stole his heart while he tried to earn her trust back.
