I gazed up at the smoking hole the bomb had made - and then I realised something was wrong. Benny lay beside me, slack and tangled like a discarded rag doll, unnaturally pale, and unbreathing. She was dead.
Nothing is ever simple, and nothing ever ends. Feed some drugs to laboratoryrats and, two hundred generations down the line, the monsters start being born.
The fragile stability of the Dellahanquarantine has been compromised, and something has escaped. Now, a man in the incipient stages of identity-collapse and a dying Bernice Summerfield have to search the byzantine cities of the Proximan Chain for an entity that killed his lover and her friend - an entity that will turn the Chain into its own version of hell.
Like The Mary-Sue Extrusion, this is told primarily in first person. However, throughout this novel are chapters entitled "Background", discussing the Stratum Seven Agent. There are also extracts from Bernice Summerfield's diary.
