The Lights of Home — Marilyn Pappano

EIGHT YEARS OF WAITING WERE OVER, and Jess Trujillo was coming home. Home to the small New Mexico town where he'd been born, and home to Caitlin Pierce, the only woman he had ever loved. But Caitlin had betrayed him in the past, and there was no reason to think she wouldn't do so again.

The chemistry between them was as strong as ever, but Jess knew better than to rely on physical attraction. He would never let himself love Caitlin again, never put his heart in her careless hands, but that didn't mean he didn't want her in his bed -- or his ring on her finger.
