After years apart, Mick and Megan O'Brien are finally ready to make it official...again. Most of their grown children couldn't be happier about their rekindled love and impending marriage this holiday season. Only Connor is a holdout. Driven to become a divorce attorney after what he views as his mother's abandonment of their family, Connor's not about to give his blessing to this reunion romance. The last thing Megan wants to do is hurt her family again. After all, is she really sure she and Mick can make it this time around? And when an unexpected delivery causes chaos, it seems only a miracle can reunite this family. Of course, it is Christmas--the season of miracles.
