LEAVE IT TO CHANCE. Eleanor “Elle” Chance, that is—the intrepid heroine of this edgy new series that transforms elements of urban fantasy, historical adventure, and paranormal romance into pure storytelling gold.   It is 1903, and the world is divided between light and shadow. On the side of light is a wondrous science that has transformed everyday life by harnessing magical energies to ingenious new technologies. But each advance of science has come at the expense of shadow—the traditional realm of the supernatural.   Now two ancient powers are preparing to strike back. Blood-sucking immortal Nightwalkers and their spellcasting Alchemist allies have a plan to cover the whole world in shadow. All they require is the sacrifice of a certain young woman whose past conceals a dangerous secret.   But when they come after Elle, they get more than they bargained for. This enterprising young woman, the daughter of a scientific genius, has reserves of bravery and determination that even she scarcely suspects. Now she is about to meet her match in more ways than one: a handsome yet infuriating Warlock named Hugh Marsh, whose agenda is as suspect as his charms are annoyingly irresistible.
