The main character of this novel is Noah Garrett, Noah is a 15 year old kid who lost both his parents to small pox and had no family anywhere nearby, therefore causing Noah to be sent out to Colorado to live with his Uncle Shelley who he had never met before. His Uncle Shelley is a soldier at the U.S. Military base at Camp Hale, A division of winter warfare soldiers called Phantoms. Shelley has Noah join the soldiers to train to fight in the war however, Noah grew up with pacifist parents so he was unsure at first. Noah then decided to train and joined the Tenth mountain division. Noah who had never seen the snow before had to first learn how to ski, then train like the rest and be prepared to be put into a battle.
The main theme the Author is trying to get across is that even when you have no experience you can still learn anything with perseverance. This is shown by Noah showing up being a pacifist and never seeing snow but eventually becoming a soldier who fights in a skiing division.
I liked how every chapter made you want to keep reading with the way they would en, The author would keep you intrigued through the whole thing.
