Will a mishap under the mistletoe lead to a lifetime of love?

The last thing Caitlin McConnell wanted to do was spend her Christmas in her hometown of Mistletoe, Texas. The town is filled with bad memories and broken dreams. When the woman who took Caitlin in during her father's incarceration begs her to come home, she reluctantly agrees, also letting it slip that she'll be coming home with her fiancé. But two days before her departure, her would-be fiancé breaks up with her, and the whole embarrassing ordeal is overheard by Tristan Harding, who comes to her rescue and gets her through the night.

Tristan has spent the last year struggling with his very public breakup and struggling to finish his novel. When his agent offers her home in Mistletoe as a refuge to write, he reluctantly agrees. But on his first day into the town, he runs into Caitlin and the two find they are the focus of the town's attention. When an innocent dinner fuels the rumors circling the them, people mistakenly think Tristan is Caitlin's fiancé. Word of their engagement gives him a break from the pressure his agent is putting on him to write, and Caitlin provides an enticing distraction to staring at a blank screen.

As they agree to keep up the charade, Caitlin begins to wish they were a real couple. Will the Mistletoe mishap lead to love, or just more disappointment for Caitlin?
