When Lucy Hannigan returned to her childhood home in Somerset Lake, one of the first things she did was join the local book club. And thank goodness, because now that Lucy's first Christmas without her mother is bearing down upon her, she can use all the help and support she can get. Especially when she has to take in a tenant and the only person interested is Miles Bruno, her ex-fiance.

As the small town prepares for the holidays and competition heats up in the Merriest Lawn decorating contest, Lucy can't help feeling like a Scrooge. Her mom loved the holidays and won the contest each year, but as much as Lucy would like to carry on the tradition, she isn't sure she has it in her to deck the halls this holiday.

Yet when Miles shows up with tons of tinsel, dozens of decorations, and lots and lots of lights, Lucy begins to wonder if maybe the spirit of the season will finally mend her broken heart.
