Brass Man

No one can outrun the past in Brass Man, is the third novel in Neal Asher's popular Agent Cormac series.
Imperfectly resurrected by Jain technology, Mr Crane is back from the dead. The brass killing machine is haunted by a violent past he can't fully forget or truly remember. He seeks to heal his shattered mind as his new master, an old biophysicist enemy of Agent Cormac, sets him on an improbable mission: to hunt a dragon on the frontier world of Cull.
On Cull, each day is a struggle for survival. Ferocious insectile monsters roam the volatile planet. And the low-tech human settlers are desperate to reach their ancestors' starship – orbiting tantalisingly out of reach. An entity calling itself Dragon assists them, but what are its real motives, and why is the biophysicist really here? Cormac must find the answers, and face multiple threats to the Polity.
Brass Man is followed by Polity Agent, the fourth book in the Agent Cormac series.
