Then Came You by Susan Coventry

A brokenhearted woman. A determined man. A new beginning.
She’s still healing.
Gillian Scott lost her fiancé over a year ago in a tragic accident. Since then, she’s focused on building her business and slowly piecing her life back together. A Latte Books, the bookstore that she owns in charming, downtown Holly, Michigan, is gaining popularity. But there’s one customer she could do without–a handsome, local cop who triggers sad memories from her past…
He’s determined to help her.
Sam Nichols is a local policeman who regularly stops by the bookstore/coffee shop that Gillian owns. He knows about her past, but he can’t bring himself to tell her. In the meantime, he feels inexplicably drawn to her, though she barely gives him the time of day. Still, sensing her vulnerability behind the strong exterior, he’s determined to break down her walls. If only she’ll open her heart and let him in…
A new beginning.
Gillian slowly forms a friendship with Sam (and his dog). But when something happens to threaten her safety, Sam comes to her rescue, and she starts to see him in a whole new way.
