I really enjoyed Dan Abnett’s novel Embedded. It has a hard SF background a million miles away from the novels he has done for the 40k universe. It has a similar feel to the KR16 background with small numbers of ‘peacekeepers’ up against shadowy insurgents. Both sides have a lot of high tech equipment. The ‘peacekeepers’ (the Settlement Office Military Directorate) are state of the art while the insurgents are backed by ‘The Bloc’. There are obvious references to current conflicts and I am hoping there will be more novels set in this universe.
