They hide in plain sight. They kill with impunity. Since near the foundation of the world, they've held the reins of government and have crushed societies under their weight. Their existence is known to ancient religions, but their role forgotten by all except themselves-until now.When tenacious journalist Will Owen begins investigating a seemingly open-and-shut case of murder, he finds a link to an ongoing story of corruption: an enigmatic woman named Sarai Rahmani. As Sarai reluctantly shows him a hidden world and reveals bits and pieces of her heartrending past, Will finds himself in the middle of a conflict between light and darkness-one in which darkness holds sway.And when that darkness closes in on Will and Sarai, their only hope is the words of an ancient historian: On the side of darkness are numbers, but on the side of light is strength unbounded.
