This stage is quite tricky for books, we're finding with DS9. I have no great suggestions. What's working for us is (a) a subscription to New Scientist (he'll browse, and then often follow up things of interest in Wikipedia) (b) DVDs, e.g. we're watching How the Earth Works together at the moment. (PS in case you haven't met Great Courses before - never buy anything at full price; they don't even expect it. The sales rotate and everything comes round at 70% off or better several times a year.)
