A thousand years ago, the mighty Cahokian civilization dominated the North American continent from its capital near modern St. Louis. From Wisconsin to the Gulf of Mexico, settlers and priests carried word of the power of their gods. People who wouldn't bow to that power were conquered or slaughtered. At the heart of the empire stood a vast city, teeming with tens of thousands. Power rested in one being, Morning Star, a god resurrected in the body of a living man. An old enemy has returned to Cahokia, bringing with him emissaries from a civilization that rivals Cahokia. It becomes apparent to the gods-possessed Lady Night Shadow Star, human sister of Morning Star, that they could be conquered by this technologically advanced culture. The fact that the living god, Morning Star, is unwilling--or unable--to play a role in the outcome is a conundrum with horrific possibilities.
