Fairly standard Cory Doctorow at this point: a plot held together by an important Idea spun out to its logical conclusion--in this case, anti-piracy legislation pushed through by big movie studios. I sound like I'm complaining (all the time, I know), but I think this is actually a strength in some of his writing for teens, particularly in Little Brother, because it introduces teens to these huge ideas in a way that's accessible and makes them understand why it's important. Not to mention planting the seed that you CAN work for change when you're still in high school. 
 This time through: Trevor has pretty much always been a filmmaker, taking snippets from tons of movies and cutting them together into a new work. He's an artist, but the whole film library at his disposal has been downloaded illegally. When his downloading gets his family cut off from the internet, he runs away to London--where he finds new friends who introduce him to the world of Pirate Cinema: underground events screening the same kind of films Trevor makes under the name Cecil DeVil. It's harmless fun, until the new Theft of Intellectual Property bills threaten to put every content creator in jail.
