Shadow prey - John Sandford

A series of ritualistic murders committed across the United
States draws Lucas Davenport into an unimaginable conspiracy of revenge in
this "classic"(Boston Globe) thriller in the #1 New York Times bestselling series.

A slumlord butchered in Minneapolis...A rising
political star executed in Manhattan...A judge slashed to death in Oklahoma
City...

Each victim has a history of bad behavior, but the only thing the killings
have in common is the murder weapon-a Native American ceremonial knife-and a
trail of blood that leads to an embodiment of evil known only as Shadow Love.
Recruited to be the lethal hand of a terrorist campaign, Shadow Love has his
own bloody agenda, one he will do anything to achieve.

Enlisted to find him are Minneapolis police lieutenant Lucas Davenport and
New York City police officer Lily Rothenburg. But despite the countrywide
carnage they needn't look far. Because Shadow Love is right behind them.
