Sable Keech is a walking dead man, and the only one to have been resurrected by nanochanger. Did he succeed because he was infected by the Spatterjay virus, or because he came late to resurrection in a tank of seawater? Tracing the man's last-known seaborne journey, Taylor Bloc wants to know the truth. He also wants adulation, power, control - and will go to any lengths to achieve them. An ancient hive mind has sent an agent to this uncertain world. Does it simply want to obtain the poison "sprine" that is crucial to immortality - and, if so, maybe Janer must find it and stop it. And Sniper, for ten years the Warden of Spatterjay, finally takes delivery of his new drone shell. It's much better than his old one: powerful engines, more lethal weapons, thicker armour. He's going to need them.
