This summer I've read a few solid books. Insomnia by Stephen King was quite excellent, but King is among of favorite authors so that was no surprise to me.

I also read Little Brother and Homeland, both by Cory Doctorow. They were very interesting and extremely relevant in today's society. It surprised me that Little Brother was written 5 years ago, reading it now would cause one to think it had came out yesterday. Best of all, they are available for free on the author's website.
