Mary vowed never to have children, and Luke has two.

He's a billionaire, but lives in a travel trailer.

Are they doomed from the start?

Mary's own mother was so awful that she vowed never to have any children of her own. That resolve destroyed Mary's last relationship, but she doubles down on what she does best: taxes and charity work. Since Mary inexplicably enjoys interpreting the inner workings of the tax code, she's content with her life.

Mary doesn't need a boyfriend.

Which is why, when a strikingly handsome electrician doggedly pursues her, she refuses to go out with him. But Luke doesn't give up easily, and Mary surprises herself by agreeing to a first date. He puts a snap and crackle in her step that she's never had before. Mary giggles over texts like a teenager and counts the minutes until she gets to see him next.

Until an issue with her charity sends Mary to the front door of a travel-trailer... and hunky Luke answers her knock. Mary's excitement fizzles when Luke's adorable children peek out from behind his legs. Luke's a widower, and Mary won't go out with him now that she knows. After all, with her family tree, she has no hope of being a decent mother. And Amy and Chase deserve the best.

Only, Luke won't let her walk away. He's only working in Atlanta for a few more weeks, and he wants to spend them all with her. Can Mary find the faith in herself to enjoy the time they have? Or will her wounded heart send her running too soon?
