Am aghast that there is a special section, though given that I have noticed sometimes recently that, say, 7 out of 10 paperback bestsellers have been this kind of thing, I suppose I shouldn't be at all suprised.
What really bothers me is that I have met people who read this stuff who think it makes them sort of morally superior to people who don't read it (like Pruni's Holocaust parallel - though actually that is often equally dodgy IMO).
I read 'A Child Called It' and just felt dirty for getting entertained by someone else's suffering, though.
