The Devil’s Engine: Hellwalkers
In the third and final book of Alexander Gordon Smith's Devil's Engine series, Marlow and Pan are in hell. Literally in hell. Faced with the awful truth of being trapped in the underworld for an eternity—of Pan being trapped—Marlow makes a final deal with the Devil, a deal to go home. But when Marlow and Pan return to Earth, they cannot close the door behind them. And all hell breaks loose. It is a war to end all wars—demonic creatures spill into the streets of New York, monsters haunt the shadows. Only the Hellraisers stand in their way, and they're not sure this is a battle they can win. They have no powers, they have no weapons. But they have each other, and they have hope, and they know how to kick ass.
Only one thing's for sure: One way or another, it all ends here.
