An early, deep snow has gifted Fishers' Harbor, Wisconsin, with a perfect setting for the holiday celebration. Unfortunately removing snow from Main Street for the parade reveals the dead tax assessor with a knife in him--containing Grandpa Gil's fingerprints.

It's clearly a setup and one that keeps Ava and Grandpa Gil under the watchful eyes of Sheriff Tollefson. Who wants Grandpa to miss playing Santa Claus in the Christmas parade and why? Who's being naughty instead of nice?

Grandpa doesn't help his case with talk of leaving town for good--words that chill Ava worse than the weather. She can't imagine life without Grandpa's warm hugs and laughter.

When vandals strike the historic shop and someone leaves Ava and fiancé Dillon Rivers for dead in the snow, Ava wonders if she may need the magical help of Santa's elves to solve the holiday folly.
