Nice review here of Orbus from Alex Cull.
Ever since reading Neal Asher’s The Skinner back in 2003, I have thought that the Prador (a race of enjoyably nasty and warlike crustacean-analogues from deep space) are among some of the best SF baddies to emerge since Terry Nation invented the Daleks. Furthermore I have believed it was high time that they had a whole novel to themselves, more or less, without any danger of the planet Spatterjay’s entertainingly horrible and ruthless oceanic fauna stealing the show. Asher’s 2006 novel Prador Moon came close to accomplishing this, the one caveat being that it was all too short, but at 438 pages, Orbus hits the bull’s-eye.
