There is a machine from the darkest parts of history, concealed in an impossible location, that can make any wish come true, and the only price you have to pay is your soul. Known as the Devil's Engine, this device powers a brutal war between good and evil that will decide the fate of every living thing on Earth. When a 16-year-old asthmatic kid named Marlow Green unwittingly rescues an ass-kicking secret soldier from a demonic attack in the middle of his Staten Island neighborhood, he finds himself following her into a centuries-old conflict between a group of mysterious protectors and the legions of the Devil himself. Faced with superpowers, monsters, machine guns, and a lot worse, Marlow knows it's going to be a breathless ride—and not just because he's lost his inhaler along the way.

Alexander Gordon Smith, author of the Escape from Furnace series, delivers yet another gripping, paranormal horror story in this series opener, The Devil's Engine: Hellraisers.
