When high-profile defense attorney William Kline is brutally murdered in his downtown Chicago office, rookie homicide detective Jake Miller is thrust into a case that will test every skill he has. What first appears to be a targeted hit quickly unravels into something far more sinister, as Jake begins to uncover dark connections to the Caruso family, a notorious mafia dynasty with deep roots in the city’s underworld.

With each new lead, Jake stumbles upon a string of cold cases, all tied to a deadly pact known as the "Blood Oath"—a secret agreement made generations ago, promising loyalty to the Carusos at any cost. As Jake digs deeper, he finds himself entangled in a web of lies, betrayal, and corruption, with the line between good and evil increasingly blurred.

Facing pressure from his department, suspicious colleagues, and deadly threats from powerful enemies, Jake realizes that the deeper he goes, the more dangerous the truth becomes. With no one to trust and his own life at stake, Jake must confront his past, expose the hidden ties between the police and the mafia, and bring justice to the victims of this bloody conspiracy—before he becomes the next target.

As the shocking truth behind the Blood Oath comes to light, Jake must face his toughest challenge yet: deciding how far he’s willing to go to take down a system built on blood and lies. This fast-paced, gripping thriller takes listeners through the seedy underbelly of Chicago, where loyalty and betrayal are two sides of the same coin, and justice isn’t always black and white.
