While Theo Florakis still eludes him, Aaron Holt agrees to come back to the agency once his conditions are met. His first target, though, is not so easy. Mikita Bykov is a master assassin who has slipped through the grasp of every organization and agency that has ever hunted him. To accomplish his mission, Holt may need to enlist the help of a new friend that assisted him in Singapore. Together, they'll try to hunt Bykov down. But will they find the assassin first? Or will Bykov eliminate them before they get the chance?
