A slumlord and a welfare supervisor butchered in Minneapolis... a rising political star executed in Manhattan... an influential judge taken in Oklahoma City... All the homicides have the same grisly method – the victim's throat is slashed with an Indian ceremonial knife – and in every case the twisted trail leads back through the Minnesota Native American community to an embodiment of primal evil known as Shadow Love. Once unleashed, Shadow Love's need to kill cannot be checked, even by those who think they control him. Soon he will be stalking Lucas Davenport – and the woman he loves...
Never get involved with a cop: Lieutenant Lucas Davenport has been warning women for years, but now he finds himself on dangerous ground with a policewoman named Lily Rothenburg, on assignment from New York to help investigate the murders. Both have previous commitments, but neither can stop, and as their affair grows more intense, so too does the mayhem surrounding them, until the combined passion and violence threaten to spin out of control and engulf them both. Together, Lucas and Lily must stalk the drugged-out, desperate world of the city's meanest streets to flush out Shadow Love – not knowing they are now the objects of his deadliest desires....
