Marnie desperately needs an assistant. As the proprietress of For the Love of Fruitcake, her successful little home bakery, her Christmas orders are piling up. She's had bad luck in the past with assistants, and vows this year will be different, especially now that she will be entering a Christmas Bakeoff competition.

Jinx needs a job and a home for the holidays. She's young, sweet, and eager to please. But she's also a jinx, just like her name.

Marnie is smitten, and hires her on the spot, but soon realizes that everything Jinx touches goes wrong, and threatens not only Marnie's business, but the Christmas Bakeoff as well.

There must be something Jinx is good at, and that is for Jinx to know and Marnie to soon figure out!
