Just finished (well, on Sunday, but I've been busy) reading Neal Asher's latest book Line War. Have to say that not only does it wrap up the Ian Cormac series satisfactorily, it's a damn fine action SF read, with all the explosions you could ever want, and an utterly thrilling sense of scale.
I really don't know anyone that does this sort of high octane Space Opera better. Highly recommended if you're looking for something entertaining, witty, and fast-paced. The Cormac books are Asimov's Foundation series strapped to a supernova.
