On a sailboat ten miles off the Florida Keys, Grace MacBride, partner in Monkeewrench Software, thwarts an assassination attempt on retired FBI agent John Smith. A few hours later in Minneapolis, a fifteen-year-old girl is found in a vacant lot, her throat slashed. Later that morning, two young men are found in their home a few blocks away, killed execution style. The next morning, three more men are found savagely murdered in the same neighborhood. As Minneapolis homicide detectives Leo Magozzi and Gino Rolseth struggle to link the crime scenes, they discover there have been similar murders in other cities across the United States.
Piece by piece, evidence accumulates that points to a suspect whose identity shocks them to the core, uncovering a motive that puts the entire Midwest on high alert and Monkeewrench in the direct line of fire. Before it’s all over, Grace and her partners, Annie, Roadrunner, and Harley Davidson, find themselves in the middle of a shocking collision of violence on a remote northern Minnesota Indian reservation, fighting for their lives.
