Yes, I read that a few months ago. Thought it was a really good book, very entertaining. After a while though I could see the ending coming, but that didn't take anything away from it. It was the author's debut novel if I remember correctly.
Its really a very good book, I just finished reading it, and really loved it.
Its about a computer hacker who goes up against DHS after a terrorist attack turns the country into a police state.
The author actually gives it away for free on his web site.
