here's something I may look into (from scitech daily):
"Put scientists, humanists, artists and countercultural explorers together and you get a New Alchemy."
I recently read The Alchemist, and am now reading it with my son, who finds it quite interesting. He's in the middle of the Narnia books, and I just finished them. The Alchemist is of a similar style, though I don't know that its author was targeting children when he wrote it. It's real cool to have my son so interested in "pondering".
