A Conspiracy of Alchemists — Liesel Schwarz

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.
