Cory Doctorow just released his newest book "Little Brother" as a free electronic book. I downloaded it the other day, and devoured it in about 2 hours that night. I don't often recommend books, every American, especially those under the age of 25, should read this book.
The story shows how fear of terrorism and modern technology could be used to turn our society into a modern-day dystopia, straight out of the pages of Orwell's 1984. Thankfully, the same technology enables free culture to thrive in an era where the Department of Homeland Security routinely reads your email and the government tortures its own citizens.
Although I've disparaged some of Cory's earlier works for being long-winded and lacking in plot, this one doesn't suffer from any of those flaws. It's fast-paced, interesting, and a great read. Read it for free here, or by it at any local bookstore.
