Winter

Kelley Quinn is the owner of Nantucket's Winter Street Inn and the proud father of four, all of them grown and living in varying states of disarray. Patrick, the eldest, is a hedge fund manager with a guilty conscience. Kevin, a bartender, is secretly sleeping with a French housekeeper named Isabelle. Ava, a school teacher, is finally dating the perfect guy but can't get him to commit. And Bart, the youngest and only child of Kelley's second marriage to Mitzi, has recently shocked everyone by joining the Marines.

Christmas on Nantucket finds Winter Street Inn owner Kelley Quinn and his family busily preparing for the holiday season. Though the year has brought tragedy, the Quinns have much to celebrate: Kelley has reunited with his first wife, Margaret; Kevin and Isabelle have a new baby; and Ava is finally dating a nice guy.

Some of the stormy weather of the past few seasons seems to have finally lifted for the Quinns. After a year apart and an ill-fated affair with the Winter Street Inn's old Santa Claus, Mitzi has returned to rule the roost; Patrick is about to be released from prison; Kevin has a successful new business and is finally ready to tie the knot with Isabelle; and, best of all, there's hopeful news about Bart, who has been captured by enemy forces in Afghanistan.

It's been too long since the entire Quinn family has been able to celebrate the holidays under the same roof, but that's about to change. With Bart back safe and sound from Afghanistan, the Quinns are preparing for a holiday more joyous than any they've experienced in years. And Bart's safe return isn't the family's only good news: Kevin is enjoying married life with Isabelle; Patrick is getting back on his feet after paying his debt to society; Ava thinks she's finally found the love of her life; and Kelly is thrilled to see his family reunited at last.
