Besides this forum, I'm reading Chemistry - The Central Science, 10th ed.
Okay, that's a joke. That's my Chemistry textbook, so don't actually go buy it, since you'll probably scream when you see the price tag.
The last actual book I read was "Waterworld" by Max Allan Collins, which is the book adaption of the most boring film ever made. I figured since the movie, which was 4 hours of ... water, was absolutely a flop, I'd read the book. The book was actually quite good, for an action/adventure kind of book. It had a kind of thrill reading it, since it brought back memories of the film and cleared up what actually happened in the film.
The last book before that, which was awhile ago, was "Steal this Book" by Abbie Hoffman. It has it's own wikipedia page, as is pretty darn weird in it's own right. I originally got it while I was in a American history class, but never got around to reading it. Most of it is outdated, as it relates to an era in history that has passed (most of the phone numbers in the book are to something else now, and many of the stores referenced are no longer in existence). It's still a good read, especially if you are interested in the counterculture of the 20th century. Content, as according to wikipedia:
The book includes advice on such topics as growing marijuana starting a pirate radio tation, living in a commune, stealing food, shoplifting, stealing credit cards, preparing a legal defense, making pipe bombs, and obtaining a free buffalofrom the US Department of Interior. It discusses various tactics of fighting as well as giving a detailed list of affordable and easy ways to find weapons and armor that can be used in the event of a confrontation with law enforcement. The book advocates rebelling against authority in all forms, governmental and corporate.
If you try anything in this book and get in trouble for it...it's your fault.
