I've only read his Golden Age trilogy, so if it's there, then no, to this 50-something it didn't stand out from everything else that happened. If it's in something else, I doubt it would. I mean, I've read Richard Morgan's ultra-violent stuff, including the gay mediæval-style fantasy one, and, well, no.

[ETA: from Google the book in question appears to be Orphans of Chaos.]

I could be an outlier though.

Well, I'm female. Could be women tend to be more sensitive to that kind of thing.

That said, I wasn't really planning to start a discussion about sexually explicit portrayals of sub-18 teenagers and whether they're ok, and I doubt I'll participate further in one. Unfortunately I don't own the book, so if anyone is curious about the details of what I was referring to, they'll have to read Orphans of Chaos (not that I recommend it on its merits). I wouldn't hazard a guess as to how much a person can be oblivious to (probably a lot), but I'd be surprised if most people's conscious, examined reaction to the sexual content (which is abundant and spread throughout the book, though not hardcore) was closer to "That is normal/A naturalistic portrayal of a 16-year-old girl's sexual feelings/Literary envelope-pushing" than to "That is weird/creepy."
