It's a think piece, and it left a lot of critics cold because there were too darn many ideas per page and the ending was a bit enigmatic. That said, it is absolutely brilliant on many levels (and it has many levels). I think I still have a review out on Amazon if you want more details. It's basically (on the lowest level) the story of what you would do if you were a genius programmer and you had a daughter you knew you'd never see, and how you'd prepare her to survive and prevail in a savage and violent world, with an interactive storybook. (That's why the subtitle is "A Young Lady's Primer.") On another level it's about the future of technology, humanity...not too ambitious, hmm? It even has sex and guns. What more could you want?
