Title: Little Brother
Author: Cory Doctorow
After being interrogated by the Department of Homeland Security after a terrorist attack on San Francisco, California, seventeen-year-old Marcus, released into what is now a police state, uses his expertise in computer hacking to set things right.
But his whole world changes when he and his friends find themselves caught in the aftermath of a major terrorist attack on San Francisco. In the wrong place at the wrong time, Marcus and his crew are apprehended by the Department of Homeland Security and whisked away to a secret prison where they’re mercilessly interrogated for days.
When the DHS finally releases them, Marcus discovers that his city has become a police state where every citizen is treated like a potential terrorist. He knows that no one will believe his story, which leaves him only one option: to take down the DHS himself.
