I happen to think the best book on Lucas is skywalking, though it is a bit outdated. For the main reason it is a unauthorized biography, so it is more truthfull than any book under lucas control, like for instance the cinema of george lucas. I will buy and read droidmaker though I don't know if it will be new or just recycled information, like the cinema of george lucas was. The author of that book actually lifted stuff from other books and magazines about lucas, and lines form lucas in televised interviews none of which was new, except some rare photos. But 50.00 was way too much money for a couple so called exclusive "pics", Some of which were already posted on hyperspace.
