Terry Brooks, best known as the author of the Shannara series, offers up a dystopian sci-fi tale set in the United Territories, which is the country that was formed after the fall of the United States. Ash Collins is a typical teenager working on his homework when he gets a vidview from his Dad. "Ash! Get out now! Go into the Red Zone. Go to Street Freaks. Don't wait!" his out of breath Dad urgently says before the call gets abruptly cut off. Ash is pretty surprised by that call since the Red Zone is the forbidden area of Los Angeles that is way too dangerous for him to have ever been there; however, when his apartment is suddenly assaulted he flees out a window without a real plan. Ash has lived a sheltered life and is ill prepared to be hunted by professionals, so when his Dad shows up on the news for supposedly committing suicide, Ash has little choice but to follow his Dad's cryptic final instructions and head into the Red Zone to find Street Freaks, whatever that is.
