Demons in Manhattan sewers. Enchanted gateways deep within the Bowery. Zombies in Harlem. Old World vampires haunting New Rochelle. Hidden Templar treasures and a hunt for the Grail across the length of a continent. Quasi-immortal Damian Paladin and adventuress Leigh Oswin pit their wits, guns and flying skills against the magical and mundane in 1930s America – and worlds beyond.
