Ha!...I know what you are getting at! There are certainly some interesting themes running through the book...I guess the whole Space Marine thing can be seen like that... Apart from his other book Inquisitor (I think) I haven't read any of the other Warhammer 40k books, are they very different from Ian Watson's? I do know that it was not considered canon by GW, later on, and I think that is why it is difficult to get hold of?
