Baby Bargain: A Once a Marine Series Book by Jennifer Apodaca:
Seeing Adam Waters is the last thing veterinarian Megan Young expects. Ex-Marine. Ex-boyfriend. And still extremely dangerous territory. But Adam doesn't know the secret Megan has been keeping from him. The secret that was created three years ago, after their last night together...
Adam returns to Raven's Cove to sell his home in a final break with the town and memories that haunt him. The problem is that his attraction to Megan is as blazing hot as it ever was. But when a vicious smear campaign against Megan turns ugly, Adam learns the truth he never knew—he has a son.
Now the only way Megan can protect her child is to strike a bargain with Adam. And it's a bargain that looks a lot like blackmail...
