As the only child of a single mom, Jenny Collins wanted nothing more than to be part of a large, rambunctious family like the O'Briens. Ironically, though, when her mother married into that family, Jenny found herself feeling more like an outsider than ever.

Now, after years in Nashville as an established songwriter, Jenny's drawn back to Chesapeake Shores to collaborate on a Christmas production…and to make peace with the past. As if that's not challenging enough, Caleb Green, the singer who broke her heart, has followed her to town, determined to win her back.

With the help of a little O'Brien holiday magic, will Jenny and Caleb find a way to make sweet music forever?
