A boy, an elf and a train. Sam Reynolds is in trouble. He's been placed in detention for fighting by the school principal and on restriction by his dad. The cause? A story. It was a story his grandfather told him of a trip he took by train when he was a boy. A trip to the great city of the north. The very north. And of a circular object he picked up in the snow dropped by a man he could see only from a distance. In the center of the object, written in large letters, were the initials SC. Santa Claus It had to be. Sam has heard the story his whole life and has seen the proof. But he wants to know for himself, to prove that what he has believed since he could remember was the truth. One night he goes looking for the train. And the adventure begins. From the author of I Am Legion, Skyfallen, and The Doom Bearers.
