It's alright. It is entertaining and keeps you reading as most Games Workshop inspired books do. It isn't a masterpiece but its a good read,
especially if you like Warhammer 40k, whether in table top games or the PC game.
Yeah I found it quite entertaining, the beginning was a bit slow but the pace quickens and it turns into a real page turner, took me 2 days to read
now I have to wait god knows how many years for the next one to come out!
