Three thousand years ago the Pale Queen was banished to the underworld. Now she’s back: meaner, crazier, and more dangerous than ever. Only one thing stands between her and the destruction of the human race—a team of twelve twelve-year-olds. So humanity is basically out of luck. It’s clearly hopeless. Seriously: a bunch of twelve-year-olds versus the greatest evil the world has ever known? Please. No way. Unless...unless Mack MacAvoy can assemble and lead the Magnificent Twelve as they discover unsuspected powers. But he’d better to do it quickly because if the Magnificent Twelve don’t win, then the world as we know it will be lost forever. And that would be a bad thing.
