From New York Times bestselling authors Nelson DeMille and Alex DeMille, Blood Lines features the return of Special Agents Brodie and Taylor who are on the hunt for the cold-blooded murderer of one of their fellow agents.

Army Criminal Investigation Agents Scott Brodie and Maggie Taylor have been separated for five months following their last assignment, a dangerous mission in Venezuela to locate and detain an infamous Army deserter. Now, in Berlin, they are reunited and tasked with investigating the murder of one of their own: CID Special Agent Harry Vance of the 5th MP Battalion, an accomplished counterterrorism agent who had been stationed in western Germany, and whose body was discovered in a city park in the heart of Berlin's Arab refugee community.

The authorities suspect this is an act of Islamic terrorism, but Brodie and Taylor soon believe there is more to this case. The reason for Vance's presence in Berlin is unknown, and as Brodie and Taylor work to discover what the murder victim was doing in the days and weeks preceding his death, they become immersed in the many conflicts and contradictions of modern Germany--the Arab refugee crisis, the dark legacy of the Cold War and the Stasi secret police, and the imminent threats of a rising neo-Nazi movement. At the same time, they are butting heads with the authorities--both German and American--and facing a possible threat from American intelligence agents who fear that Brodie and Taylor might have learned too much about US clandestine operations during their mission in Venezuela.

Ultimately, Brodie and Taylor realize that the murder of Harry Vance was merely the prelude to a much more sinister future event--unless they can unravel the mystery in time to stop it.
