Orbus — Neal Asher

In charge of an old cargo spaceship, the Old Captain Orbus flees a violent and sadistic past, but he doesn't know that the lethal war drone, Sniper, is a stowaway, and that the past is rapidly catching up with him. His old enemy, the Prador Vrell, has seized control of a Prador dreadnought and is now seeking to exact vengeance.

Their courses converge in the Graveyard, a place filled with the ruins left by past genocides and interplanetary war. A place that is home to the Golgoloth, monster to a race of monsters, and where a centuries-long cold war is being fought.

Meanwhile, the terrifying Prador King is coming, prepared to do anything to ensure certain deadly secrets stay buried ... and somewhere out there something that has annihilated civilizations is stirring from a slumber of five million years.

The cold war is heating up. Fast.
