River Road - Jayne Ann Krentz

It's been thirteen years since Lucy Sheridan was in Summer River. The last time she visited her aunt Sara there, she'd been dragged away from a wild party by the guy she had a crush on. Obviously Mason Fletcher was the over-protective type who thought he had to come to her rescue. Now, Lucy learns there was more to the story... Mason had saved her from a very nasty crime that night. Soon afterward, Tristan, the cold-blooded rich kid who'd targeted her, disappeared mysteriously, his body never found. Mason is still a protector at heart, a serious (and seriously attractive) man. And when he and Lucy make a shocking discovery inside Sara's house, Mason's quietly fierce instincts kick into gear. He saved Lucy once, and he'll save her again...
