About: 

"She's the most powerful steam engine in the world," Will's father tells the reporters. "She'd pull the moon out of orbit. As for her length, it's more than seven miles..."

When Will Everett boards The Boundless he expects the ride of his life - not a fast route to death. But when the key to the train's secret cargo falls into his possession he finds himself hunted by ruthless killers. As the great train hurtles across the country he will need all his wits to elude his pursuers - and keep himself alive.
