When Justin Flinchley loses his job on Black Friday, he thinks his life is over. Without money to pay rent, he'll be celebrating Christmas on the streets unless he can manage to find a new job by the end of the week. But in the middle of his frantic job search, he comes across an ad that sounds too good to be true:

"Air courier desperately needed. No experience necessary, we will train you. Must be willing to relocate."

The moment Justin applies, he is whisked away to the North Pole, where he's given a pair of antlers and told that he's the latest addition to Santa's team of reindeer! An ancient evil is plotting to shroud the world in darkness, and only Santa's gifts can keep the light of hope shining bright enough to push it back. Justin has less than a month to learn how to fly before Santa's yearly trip around the world. The fate of Christmas–and the entire world–depends on him.

There's only one problem: he's afraid of heights.
