The Second Sister — Carrie Weaver

You can't change the past...
Colleen Davis is the younger sister, the second sister, the one who stayed behind. Now her dying father has one final wish -- to reconcile with his elder daughter, Violet, and Colleen has no choice but to help. But that isn't going to be easy, because once she gets to Violet's, she finds Sheriff Vince Moreno standing in her way.

But can you build a future?
Vince has sworn to take care of Violet during her difficult pregnancy -- and traveling four hundred miles for a bittersweet reunion that won't make up for the past doesn't strike him as a great idea. But Colleen refuses to let them wait until the baby is born, meaning Vince has to go with them -- back to the hometown he doesn't want to see again. Along the way he realizes that Colleen doesn't come second to anyone...but before he can even act on his feelings he has to confront the tragedy of his own past....
