SPOILER: Plot details or story follow.
Grace Goodwin is a young girl who is determined to remove herself from the Naughty List, a distinction which she blames on her toddler brother. She manages to capture a Fruitcake Conduct Calculator, left behind in the aftermath of an ambush she set for the Coal Elves. Using the screenname of “jinglesmell 1337” she attempts to hack into the Database Tree Farm at the North Pole. Her efforts cause Wayne and Lanny (along with Wayne’s younger brother Noel, a Coal Elf) to be dispatched on a secret mission…but Grace has something special planned for their arrival!
