From publisher description:
As baby elves, you heard the tales of the terrible gnomes that used to live at the North Pole. Once considered an ally of the elf, gnomes also enjoyed making toys and trinkets. When Santa Claus opened his workshop, he decided that the toys manufactured by the gnomes were too risky, too explosive, and too dangerous for children. He relegated gnomes to the gardens of humans where they would guard plants. They’ve spent years plotting their revenge.
Now, as adult elves, it is early on Christmas Eve and you hear the news that your boss has been kidnapped by gnomes! You know the score. You round up your friends, as a group of misfit elves who have always done St. Nick’s dirty work, you strategize to find him, and save Christmas!
You’re elves on a mission - retrieve your boss and put those gnarly gnomes out of their misery! Even though it has been a tough year for all of the elves, you are guided by the smallest glimmer of holiday cheer.
