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 realises 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 which 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 . . .
