I would highly recommend it... the first four books (Enders Game, Speaker for the Dead, Xenocide, and Children of the Mind) are much better than the later concurrent-sequel / whatever you would call them books.
As for the original question... no, I cannot think of anything which could be remotely construed as pornographic; and I would rate myself as quite conservative when it comes to that sort of thing. Violence, mature situations, absolutely. I would say that it is appropriate for kids somewhere around 10 - 12+ years, depending on the child in question.
