Let me get this out of the way: if you're not a "computer person," someone with more than a vague knowledge of computer networking technology, Brain Jack, by Brian Falkner, is probably not the book for you. If, however, you ARE such a person, Brain Jack will start off as the kind of thriller that you think you will love, but its ending, like so many other cyber-thrillers, feels rushed and absurd. Don’t get me wrong--you'll enjoy reading it, but don't expect anything too deep from this book.
Sam is the generic hero of our story. He's 17; he's a computer prodigy; and he's going to save the country from itself. The world of Brain Jack is set only a few years into our future. Falkner does a good job of building a world that, initially, is entirely conceivable based on our present. Computer technology is even more prevalent, and its consequences all the more potent. Las Vegas has been the victim of a nuclear attack that has left it in ruins, and the rest of the country is decaying under strict martial conditions.
