Book Four in the Black Flagged Series) With the most recent bio-terrorism threat against the United States neutralized, and Dr. Anatoly Reznikov in secret custody; CIA Deputy Director Karl Berg proposes a more permanent solution to prevent future attacks. A covert raid by General Sanderson's Black Flag unit deep inside Russia...to destroy a bio-weapons program that should have ended with the Cold War. The United States isn't the only nation looking to tie up loose ends. The sudden abduction of a CIA officer in Stockholm exposes the Russian Foreign Intelligence Service's (SVR) ruthless campaign to discover the truth behind the massacre of an elite Spetsnaz team sent to eliminate Reznikov...and permanently bury his knowledge of Vektor's sinister purpose. When the SVR investigation takes a turn that could threaten the mission against Vektor Labs, Berg goes "off the books" like never before to even the odds. Through an intricate web of unsavory alliances, deviously orchestrated political maneuvers and shockingly brutal black-ops sanctions, Karl Berg will set in motion an unstoppable chain of events with the potential to ignite a new Cold War.
