Polity Agent — Neal Asher

From eight hundred years in the future, a runcible gate is opened into the Polity and those coming through it have been sent specially to take the alien maker back to its home civilization in the Small Magellanic cloud. Once these refugees are safely through, the gate itself is rapidly shut downbecause something alien is pursuing them. The gate is then dumped into a nearby sun. From those refugees who get through, agent Cormac learns that the Maker civilization has been destroyed by pernicious virus known as the Jain technology. This, of course, raises questions: why was Dragon, a massive biocontruct of the Makers, really sent to the Polity; why did a Jain node suddenly end up in the hands of someone who could do the most damage with it? Meanwhile an entity called the Legate is distributing pernicious Jain nodes and a renegade attack ship, The King of Hearts, has encountered something very nasty outside the Polity itself.
