Holiday time is magical in Sea Harbor, as the Seaside Knitters turn winter yarns of deep reds, greens, and golds into gifts. But when murder comes to this small New England town, they must set aside their needles to pursue justice-and restore joy to the season.

In Sea Harbor the scent of snow fills the salty air, and at Izzy's Seaside Yarn Studio, the Knitters feast on cookies, knit their gifts, and plan their holiday gatherings. Across town, Mary Pisano is sparing no expense to transform the estate she inherited from her grandfather into a bed-and-breakfast. When the Pisano family gathers for their annual meeting, Mary offers to put up her cousins in the refurbished family home, hoping to dispel any ill will over her inheriting the estate. But hard feelings are likely the cause when Mary's cousin Pamela is found dead on the B and B's snowy back porch.

While the Seaside Knitters begin unraveling the case, Izzy Chambers is knitting her brow over her own mystery-the mystery of love. As the holiday draws nigh, the four friends will need all their crafty know-how to solve the crime and restore holiday peace-and the magic of mistletoe-to Sea Harbor.
