Captain Blite and Agent Cormac thought they had defeated the malevolent AI Straeger. But Straeger’s mission to plunge the galaxy into a devastating war is far from over. With a twisted p-Prador army bred from the Spatterjay virus, Straeger sets his plans in motion. Meanwhile, in the war-struck world of Yossander’s Hold, Blite and Cormac are trapped in a maelstrom of betrayal and violence. They must fight their way through the chaos as they seek to repair Blite’s damaged ship. But their escape requires resources from the Bracken, and aboard that ship, a terrifying transformation is underway. Recognizing the threat posed by the p-Prador, the Prador Kingdom and the human Polity’s ruling AI form an uneasy alliance. But with Straeger’s plans unfolding and reality itself under threat, the galaxy is poised on the brink of destruction.

Captain Blite knows that someone, or something, is trying to kill him. But a device he possesses, known only as the dark diamond, won't let that happen. After surviving a series of catastrophic accidents and assassination attempts, Blite realizes that whenever he dies, the dark diamond reverses time to a moment before his death. He must go through the traumatic experience again and again until he escapes. Every encounter Blite survives generates a time flash that reveals potential futures. This extraordinary phenomenon attracts the attention of Polity agents and the crab-like p-Prador who wish to acquire this power for themselves. Hunted across space and time, Blite must uncover the true nature of the dark diamond before it causes his destruction.

Ottanger is a rebel and mutant on an Earth governed by a ruthless Committee. But after its Inspectorate experiments on him, Ottanger realizes the mutation allows him to reach alternate worlds. The multiverse is revealed in all its glory and terror --- and he understands that he finally can flee his timeline. Then Ottanger meets the Fenris, an evolved human, visiting his Earth from the far future. He’d engineered the original world-walking mutation, so those altered could escape the Committee’s nightmarish regime. Yet this only worked for a few, and millions continued to suffer. And Ottanger sees that that Committee will become unstoppable if not destroyed. However, the Fenris has drawn yet another threat to Ottanger’s Earth. With the power of its trillion linked minds, it craves world-walking biotech and will do anything to get it.
