Secret Heart: The Montgomerys #1 (Hearts of Three Rivers #4)
Amity Lassiter

Single mother and perpetual girl-from-the-wrong-side-of-the-tracks Layla Sullivan is barely holding together the life she’s building for herself and her son. She’s got shift work, squeaky cupboards, a big fat secret, and no time for Nate Montgomery to come waltzing into her life, making her wish for things she can’t have. But this cowboy is as bull-headed as he is sexy, and it doesn’t take a rocket scientist to figure out that having an extra warm, handy body in her house isn’t a bad thing—especially when it belongs to her baby’s father.
When Layla’s family drama comes back to bite her, exposing her secret and threatening the happy little bubble they’ve created, Nate feels bound to repeat the sins of his father. But he’s never been one to give up, and this little family might be just the new life he’s looking for.
