The final, thrilling conclusion to #1 The New York Times bestselling author Anthony Horowitz's masterful series -- now in paperback!
All that's left is the endgame . . .
For a moment, it looked like they had won -- the five Gatekeepers had united -- and then a deadly typhoon tore them apart, scattering them through the door and across the world.
Ten years into the future, the Gatekeepers find themselves struggling through a desolate world to find one another; to stop the evil force that waits for them; to save the world as they did ten thousand years ago. With enemies dogging their every step and the doors broken, the Gatekeepers' only hope is . . . Oblivion.
