Preparing for another holiday season in Nantucket, the Quinns are optimistic that despite a health scare for Kelley, this year's celebration will be their best in ages. After a year apart, and an ill-fated affair with the Inn's old Santa Claus, Mitzi has returned to rule the roost; there is hopeful news about Bart, who has been MIA in Afghanistan; and love is in the air as Kevin and Isabelle are preparing to get married. But as the family gathers together, a powerful blizzard bears down on the Eastern seaboard. With a wedding, an emotional reunion, and enough holiday drama to test the closest of family bonds, the story proves that when the holidays roll around, you can always go home again.
