The "Ghost Map" sounds interesting. I'll note it for the future. Glad another kid is interested in diseases, "officially cool".

I go to the library book sales and used book stores and over time you can often find some inexpensive copies of some of the Mensa-type books, since they're "tried and true" and floating around. Then you can bring them home and put them on the shelf and on a rainy day if no electronic time (hee hee) they'll be forced to drift over and pick up a book.
