Welcome to Spatterjay…where sudden death is the normal way of life;

To the remote planet Spatterjay come three travellers with very different missions. Janer is directed there by the hornet Hive-mind; Erlin comes to find the sea captain who can teach her to live; and Keech — dead for seven hundred years — has unfinished business with a notorious criminal.

Spatterjay is a watery world where the human population inhabits the safety of the Dome and only the quasi-immortal hoopers are safe outside amidst a fearful range of voracious life-forms. Somewhere out there is Spatterjay Hoop himself, and monitor Keech cannot rest until he can bring this legendary renegade to justice for atrocious crimes committed centuries ago during the Prador Wars. Keech does not realise that Hoop's body is running free on an island wilderness, while his living head is confined in a box on an Old Captain's ships. Nor does he know that the most brutal Prador of all is about to pay a visit, intent on wiping out all evidence of his wartime atrocities. Which means major hell is about to erupt in this chaotic waterscape.

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 so much else — adulation, power, control — and will go to any lengths to achieve them. An ancient hive mind, almost incomprehensible to the human race, 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.

Meanwhile, still faced with the ennui of immortality, Erlin has her solitude rudely interrupted by a very angry whelkus titanicus, and begins the strangest of journeys. Deep in the ocean the Spatterjay virus has wrought a terrible change that will affect them all. Something dormant for ten years is breaking free, and once again the aftershocks of an ancient war will focus on this watery world. 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.
