Chicago Blue is the story of a family. 

The son of Chicago's ex-chief of detectives, Billy Harney was born to be a cop. So was his twin sister, Patti. The decorated homicide detectives play it by the book. Their father, Daniel Harney, never did. He’s always known how to disappear someone. Especially himself. 

Chicago Blue is the story of a police force. 

After a long and mysterious absence, Daniel Harney returns to find his former PD under siege. The governor and mayor have been shot. A spree killer is targeting police officers. Can the city be Harney’s once again? 

Chicago Blue is the story of a city. 

Thrumming with conflict from the West Side to Mount Greenwood, from Woodlawn to the skyscrapers downtown, this is a story as twisty as the Chicago River. The citizens of Chicago are together for better or worse―if they don’t kill one another along the way. 

Chicago Blue is an inventive, propulsive thriller about power, corruption, and destructive secrets.
