Obligatory "you may also like" reccomendation: Ignition! by John D Clark ( http://www.sciencemadness.org/library/books/ignition.pdf ), which is an unofficial history of rocket fuel. A mixture of hard science and lab-exploding anecdotes.
It's actually kinda hard to find - at least harder than I'd expect for such a well recommended book. Time to start rummaging through my local book stores :)
