Railhead

Step Aboard - the Universe is Waiting.
The Great Network is a place of drones and androids, Hive Monks and Station Angels. The place of the thousand gates, where sentient trains criss-cross the galaxy in a heartbeat.
It is also a place of great dangers - especially for someone who rides the rails and rides his luck the way Zen Starling does.
Once Zen was just a petty thief, stealing to support his family and living by his wits. Now everything has changed. Zen is still a thief - but it could be that the key to the whole universe rests on finding out what else he is . . .
This is an epic story with huge scope and film rights have already been bought by Warner Brothers.
