Driving along the freeway, Shane Scully glances over and sees Jody Dean, his oldest friend and LAPD colleague, at the wheel of an adjacent car. Why is Scully so surprised? Because it's been two years since Jody committed suicide in the Rampart Division parking lot by blowing his brains out with a service revolver. Shane served as a pallbearer at the funeral.
What Scully will discover is that Jody and five other cops who are supposed to be dead are anything but; originally sent deep undercover to bust an extremely violent criminal network, they have become the LAPD's worst nightmare. Calling themselves the Vikings, they are rogue cops who know how the system works. In order to penetrate the group and set his cover, Scully is supposed to shoot his fiancée, Alexa. The setup goes awry and Shane finds himself looking down at his future wife's body. He is soon driven into the corridors of near-madness and into the bed of an extremely beautiful and utterly ruthless corporate seductress who threatens to destroy his soul.
Shane's desperate and deadly undercover journey takes him from the embrace of Alexa and his teenage son, Chooch, to the Caribbean island of Aruba--to the decadence of Columbia's opulent palaces and the desperation of its deadly streets. Sergeant Scully is driven to the psychological brink, his life in the hands of the most dangerous killer he's ever known-his closest childhood friend.
