Excellent novel Mr Bennett, I love hard sci-fi, especially near-future and body modification. Elements that I loved in Alistair Reynold's 'Revelation Space' and K.S. Robinson's '2312' and to a lesser extent Iain M. Banks Culture novels. I felt your novel stands quite comfortably with these writers. I would love to see more work from this universe.
In fact my only complaint would be that it seems to be more marketed as a superhero book, when it clearly isn't. (much to my relief!)
