I know there are lots of threads about the books and I've watched series 1. DT2 told me the other day that he was going to get the book from the library. I told him that it isn't suitable. Too many beheadings/violence (gore doesn't' bother him) and far too much sex (he doesn't seem bothered either). I've not actually read the book so don't know how graphic the scenes are. I remember being forbidden to read Sydney Sheldon's Bloodlines as a teenager so went and took it off the bookshelf anyway.
Just want to give him a bit of guidance.
