Ryan Kaine is on the brink…
When a number of “wet teams” protected by a government kill order target every member of former Royal Marine, Ryan Kaine’s troop and whispers of betrayal reach his inner circle, Kaine is forced to act and launches an immediate counteroffensive.
As old enemies resurface and new threats emerge, the walls close in and Kaine must fight to expose the truth and protect those who depend on him.
When assassins come for Kaine’s friends, how will he protect them and innocent bystanders, and ensure the existential threat is dealt with—permanently?
With over half a million copies sold, the Ryan Kaine series has become a must-read for fans of Lee Child, Jack Lively, and Robert Ludlum.
