Sentinel Five (The Redaction Chronicles Book 2)

After the Chief of the Secret Intelligence Service is assassinated, a terrorist organization plans to unleash a weapon of apocalyptic proportions and bring the British government to its knees. A deniable team is assembled to hunt down the terrorists. Called back from obscurity to lead them is Jack "Gorilla" Grant: a freelancer with a Smith and Wesson' 39 and cut-throat razor. And he's ready to settle the score in his own, brutal fashion. The Sentinel Five team turns their gunsights to the East, and enters a killing ground of death.
