Publisher's Synopsis
Earth has been conquered by an alien race known as the Assembly. The human adult population is gone, having succumbed to the Tone - a powerful, telekinetic super-signal broadcast across the planet, which has reduced them to a state of complete subservience. But the tone has one critical flaw. It only affects the population once they reach 21 or 22 years old. This means that there is one group left to fight - teens.
