I have only read one American one, many years ago, which was interesting and showed the gaps in the system and the law, as much as focused on the abuse, abit like the film/book Monster.
I thought that this was a good thing as most people thought that the system for dealing with child abuse was adequate.
I don't think that some people realised how bad child abuse could be, or that it could be happening next door.
I have read nearly every bit of true literature on the holocaust and the death/concentration camps, though, which some would say 'was sick', to do,also.
There seems to be a need by people who have gone through trauma to tell their stories, rather than them be hidden.
Rather than the book stands be called 'tragic or miserable lives', i would like them to be more positive names, such as 'survivors stories', etc.
