My Ex for Christmas by Bobbi Maclaren

When her boss opens a new ski resort in the province she used to call home, Hadley Knight is hopeful she can still avoid her past. But her luck runs out when she finds herself in a dingy small-town bar being served by her ex.
Brooks Dawson lives a simple life. He works his shifts as a bartender and helps his mom take care of his sisters. He’s content with his routine—until his ex walks into his bar. Suddenly, nothing is the same.
Hadley and Brooks parted ways eight years ago, but now that she’s back, he doesn’t want to let her go. Too bad she has a habit of leaving. But when a new job opportunity opens up for her, Hadley has to decide whether running from her past is worth sacrificing her future.
