A final, special mention, for the book reviewers at arrse.co.uk (Just click ‘Home’ if you end up at an error page) for not laughing me out of town, but giving good advice and suggesting the wiki site where maps will be added constantly. They take a few hours to create so bear with me and visit also. Maps, more coming all the time.
The Series Facebook page has other bits and pieces, plus if you have any queries you are guaranteed a quick response. Armageddon's Song on Facebook.
