Like so many schools today, Herrington High has passed its prime. Its walls are grimy, its textbooks outdated, its teachers burned out. Yet its corridors are packed with the future of America - loners, leaders, hipsters, nerds, brains and jocks. Like teenagers everywhere, they struggle with parents who don't get it, teachers who never had it and hormones that won't quit. But the students at Herrington High face a greater challenge - saving the world from alien domination.
