Brass man - Neal L. Asher

On the primitive world of Cull, a knight errant called Anderson is hunting a dragon, little knowing that far away someone else (now more technology than human flesh) has resurrected a brass killing machine called 'Mr Crane' to assist in a similar hunt encompassing star systems. When agent Cormac learns that this old enemy still lives, he sets out in pursuit aboard the attack ship Jack Ketch . whilst scientist Mika begins discovering the horrifying truth about that ancient technology ostensibly produced by the alien Jain.

Meanwhile, for the people of Cull, each day proves a struggle to survive on a planet roamed by ferocious insectile monsters, while they slowly construct the industrial base that may enable them to escape to their forefathers' starship -- still orbiting far above them. But an entity with questionable motives, calling itself Dragon, assists them with genetic by-blows created out of humans and the hideous local monsters. And now the planet itself, for millennia geologically inactive, is increasingly suffering earthquakes .
