Come with me, Zen Starling, she had said. The girl in the red coat. But how did she know his name?
The Great Network is a place of drones and androids, maintenance spiders and Station Angels. The place of the thousand gates, where sentient trains criss-cross the galaxy in a heartbeat.
Zen Starling is a petty thief, a street urchin from Thunder City.
So when mysterious stranger Raven sends Zen and his new friend Nova on a mission to infiltrate the Emperor's train, he jumps at the chance to traverse the Great Network, to cross the galaxy in a heartbeat, to meet interesting people - and to steal their stuff.
But the Great Network is a dangerous place, and Zen has no idea where his journey will take him.
