All Amy Casey wants for Christmas is to paint. She needs five new paintings for the holiday show at her local art gallery, but between her two teenage sons, her needy ex-husband, and her overbearing parents, she hardly has any time for herself. Luckily, her best friend has the perfect solution: a vacant family lake house in North Texas, all hers for two weeks of distraction-free painting. Or so she thought.

Turns out professional golfer Harrison Neely also rented the lake house so he can spend the holidays rehabbing the injury that has put his career--and life--on hold. Despite the booking snafu, both Amy and Harrison (along with Amy's old blind dog and the army of child-sized nutcrackers residing in the living room) agree to share the festive lodging.

When an impending snowstorm has the two cozying up by the fire, sparks fly in more ways than one, and they open up to each other, unwrapping secrets and stories they've never shared before. But Harrison is expected back on the tournament circuit after the holidays, and Amy's family needs her. As their departure date looms and her family and his manager press them for answers, they'll have to decide if this December to remember has been a fun holiday fling, or if they've found a Christmas miracle at middle-age: true love.
