I see. Thank you for the explanation ... not offence intended but I had read those that I mentioned by the time I was twelve, through choice. TBH and as I have said on this forum and in "the other place" I have never seen science fiction as particularly adult reading. My little boys (aged 9 and 7) love all that stuff. It simply has never appealed to me. I have tried but it does nothing for me at all.
Each to their own I guess ~ certainly not something to fall out over.
