She's My Kinda Of Girl. Something New, #4.5

In high school, Darcy Miller and Griffin Strong burned fast and hot. Then Darcy shook off the small town of Revival, Illinois, leaving Griffin behind. Ten years later, Darcy is exactly who she planned to be: a New Yorker with a sharp tongue, a sex-positive writing career, and a life built on designer cocktails. The past is firmly in her rearview mirror. until she learns the town plans to seize her mother's house right after the holidays.
And the person responsible? None other than her ex. The new mayor!Griffin Strong might have reformed his bad boy ways and become a respectable member of society, but that flies out the window when Darcy Miller walks into the first annual Revival Christmas party. She's everything he'd ever dreamed she would be-smart, fiery, and determined to stir up trouble. But Griffin is a man with a mission, determined to save the town he loves.
And Darcy is making that very difficult. Especially when she looks at him like she never left. Especially when she reminds him exactly how good it feels to be bad. Some sparks never really go out. And this Christmas, Darcy and Griffin are about to find out what happens when old flames get too close to the fire again.
