Tizzy Scamperpop has for the last one hundred and seventy-four-years wanted to win Toy Maker of the Year, and this year he’s finally poised to beat the elf who always wins.

Now he’s one broken train away from victory—and one terrible decision away from disaster. When he swaps toys to hide his mistake, he wins the prize… and lands on the Naughty List.

Then Tizzy makes it worse. Much worse. He takes the list before Santa can see it. Then he loses it. Now the North Pole is heading for a holiday meltdown, and every present in Santa’s bag hangs in the balance. If Tizzy can’t fix his mistake—he’ll ruin Christmas for everyone.
