After an epic, two continents, two-country, multi-city battle with Adam Clark's ruthless CTAC assassins, Sergeant Hammer's rogue Special Forces operators, the storied Red Army Faction, homicidal Latin Kings, and brutally corrupt prison officials belonging to the violent Brotherhood of the Iron Hammer, Dexter, and his S.W.O.R.D. operatives have emerged victorious. However, Dexter's suspicions about the level of funds and technology available to the team are confirmed when Harold Ashford orders him to have S.W.O.R.D. sever all ties with the Urban Justice Research Institute and prepare for a new mission with their true employer. In Langley, Virginia, CIA Associate Deputy Director of Operations Marc Lubet, who is also secretly a member of CTAC, knows that Dexter's team raided CTAC headquarters in Dallas and possibly knows that his name is in the files that they downloaded. With his eyes set on becoming the Director of the CIA, he devises a plan to free Sergeant Hammer and his rogue Special Forces operators from military custody to use them to eliminate Dexter and his team and recover the files they stole. To make things even more complicated, Colonel Diamond is about to disrupt Dexter's life by preparing extreme measures that are meant to transform him into what he needs to be to complete his new, mysterious mission. Dexter is forced to delve deep into the darkest areas of his psyche and instincts as the Colonel sends him on a perilous operation in the most dangerous place in the world, and mercilessly forces him to face his greatest fear. Dexter's powerful employer emerges from the shadows and tasks him to attempt one of the greatest top-secret missions in modern history, which if successful, will have a lasting global impact. But first, he will have to survive the deadly trials set by his father, and the multiple unsanctioned assassination attempts by Marc Lubet's unrelenting contract mercenaries.
