Widowed Sloane Whittman never expects to find love again, but it happens when she meets up with Seth again—the man her dead husband and everyone else on Cape Cod call Joe. Christmas is coming, and Sloane is all for giving her son his Christmas wish for a new dad. The solution seems clear, marry Seth, but several glitches throw a monkey wrench into her plans.

Seth is madly in love with Sloane but worries she might feel he's less than a man because of his life-changing injuries from a shark attack. His sister is in a coma, and his niece Janie is wishing for her mom to wake up for Christmas. He can only pray for a Christmas miracle.

Will everyone get their Christmas Miracle? Or will the Grinch steal their dreams?
