In a society which is a bit too close for comfort to ours, Marcus, a 17yo teenager, happens to be in the wrong place at the wrong time, gets accused of terrorism, is put in jail and interrogated. He ends up being released, and fights against the surveillance society he's living in. Quite nice, believable when it comes to technical stuff, sometimes even didactic (slightly heavy-handed at times though). The current events make the whole thing all the more believable and timely, which makes it somewhat scary.
