Daddy December by Linzvonc

Ten years ago, Noelle made the hardest decision of her life—she left the small town of Winterburg, pregnant with her best friend’s brother’s baby. Nicholas Christian had a bright future at Oxford, and Noelle couldn’t bear to hold him back. Now, she’s back in town with her daughter, Holly, just in time for Christmas. She’s done her best to move on, but when Nicholas returns from England, the past comes rushing back.
As Nicholas discovers the truth about Holly, both he and his family are devastated by the lost years. But while the truth may have come too late, the spark between Noelle and Nicholas has never died.

With the magic of Christmas all around, can they find forgiveness and a way forward—together as a family?
