Deck the Shelves by Joelle Cullen

Alice Evans is trying hard to keep the Holly Jolly in Christmas this year. After her longtime boyfriend decides he wants to see more of the world (without her, that is), she is left figuring out how to piece hers back together.
But no one wants a Grinch bringing down the office spirit, so her boss convinces Alice to take a leave of absence from her role as fashion executive at a London marketing firm. She returns home to the small village of Berkingsley and her parents’ bookshop and soon realizes that there are bigger problems than not having a boyfriend to share Christmas morning with.
Hiding her breakup from her family, she learns that her parents are also keeping a secret, one that will take the help of the entire village to resolve. With the help of her friends and (possibly) a new love interest, Alice is determined to bring joy to herself and her parents this holiday season.
What kind of miracle will it take to make it a Happy Christmas for all?
