Heh, for a minute there I thought you meant Warhammer 40k books specifically, and I thought that was a pretty funny thing to be scraping from HN :)
Recommendations would include comments like, "This novel is really the one that ties the previous 37 books together." or "You might want to skip the next dozen books if you're squeamish about things that ooze."
Then there is there is the unashamed embrace of over-the-top in so many different ways.
