Chasm City
by Alastair Reynolds

Description:
The once-utopian Chasm City - a domed human settlement on an otherwise inhospitable planet - has been overrun by a virus known as the Melding Plague, capable of infecting any body, organic or computerized. Now, with the entire city corrupted - from its people to the very buildings they inhabit - only the most wretched, grim sort of existence remains. And it is through this city that security operative Tanner Mirabel must pursue the object of his vendetta: a lowlife postmortal named Argent Reivich. But as Reivich keeps slipping through the cracks of Chasm, Tanner will be taken far beyond the mere settling of a score - to come face to face with a centuries-old atrocity that history would rather forget.
