There has just been a terrorist attack in San Francisco. The Bay Bridge is gone and part of the BART is destroyed. Marcus and his friends are seen near the bridge and are arrested by the DHS - Department of Homeland Security. That's when the nightmare begins for Marcus and one of his buddies, Darryl and that's when this book gets so exciting, yet scary. Homeland Security holds people in secret. They use waterboarding torture against American citizens. They secretly send prisoners overseas so they can be further tortured. Most American citizens are content to let their privacy and freedom be taken away, not knowing what is going on in their back yard. All these events resemble news from today's world.Marcus is an unlikely hero. He is a geek who uses modern technology to fight the DHS. He is frightened by what he sees and tries to fight against those who want to take away freedoms under the guise of protecting citizens from terrorists. At first, he fights secretly, but then decides (or has it decided for him) to fight openly. The author of this book was inspired by 1984, which he claims to have read thirty or forty times. He was also inspired by hackers. The first few pages of the book is pretty technical. Marcus tried to explain many computer concepts and lingo in the beginning so that we understand everything that will occur later. I didn't understand all of it, but it didn't detract much from understanding the dilemmas that Marcus faced. Once the terrorist attack occurred, the book was hard to put down.I would have given this book 4 1/2 stars if Goodreads allowed. I didn't give it 5 stars because the technical aspects can be difficult to comprehend for non-geeks and because of several sexual scenes that weren't really necessary to move the plot along.
