Eleven-year-old Nikolas-nicknamed "Christmas"-has received only one toy in his life: a doll carved out of a turnip. But he's happy with his turnip doll, because it came from his parents, who love him. Then one day his father goes missing, and Nikolas must travel to the North Pole to save him.
Along the way, Nikolas befriends a surly reindeer, bests a troublesome troll, and discovers a hidden world of enchantment in the frozen village of Elfhelm. But the elves of Elfhelm have troubles of their own: Christmas spirit and goodwill are at an all-time low, and Nikolas may be the only person who can fix things-if only he can reach his father before it's too late.
