Railhead Trilogy

The Great Network is a place of drones and androids, maintenance spiders and Station Angels. The place of the thousand gates, where sentient trains crisscross the galaxy in a heartbeat. Zen Starling is a petty thief from Thunder City. So when mysterious stranger Raven sends Zen on a mission to infiltrate the emperor's train, he jumps at the chance to cross the galaxy in a heartbeat. But the Great Network is a dangerous place....

There was nothing, and then there was a train. A train with two passengers: a petty thief from a dead-end town, and an android girl who could be more human than the rest of us. Join Zen and Nova as they find out what really lies beyond the end of the universe.... Full of extraordinary beings and utterly real, complex characters, this is a stunning step beyond the universe we already know....

What happens after the adventure of a lifetime? For Zen, it's a safe, comfortable life of luxury. But it's not what Zen wants. He misses the thrill of riding the rails, of dodging danger and of breathing the air of different planets. Most of all of course he misses Nova - lost to him forever in a distant world. But then one day a mysterious message arrives - and that's all Zen needs to head right off, ready for anything. Except that no one could be ready for what he finds....
