Iran's Islamic Revolutionary Guard Corps is reeling from a devastating attack on its covert training center in Bandar Deylam, Iran. In retaliation Iran's Supreme Ruler unleashes an ultra secret weapon - Unit 400. This cadre of trained assassins has its roots in ancient Persian culture, when Ismaili leader, Hassan al-Sabbah, unleashed the Hashashin from their mountain fortress at Alamut to assassinate political and religious foes. One man stands in their way - former Navy SEAL Logan Alexander. In this exciting sequel to award winning author, T.L. Williams debut novel, Cooper's Revenge, Logan and his Special Forces team travel to Europe and South America in an effort to track down the elusive killers before they can strike again.

Navy Seal, Logan Alexander, is trying to put his life back together following a career-ending injury in Afghanistan, when he learns that his younger brother, Cooper, has been killed in an ambush while on patrol with his Ranger unit in Iraq. As Alexander delves into the circumstances leading to Cooper's death, he learns of the role that the secret arm of the Iranian Revolutionary Guard Corps, the Qods Force, plays in exporting terror. Alexander vows to avenge his brother's death. With the financial backing of a Kuwaiti billionaire, and a group of like-minded Special Forces operatives, Alexander conceives a plan that takes his team to the Sonora Desert, Europe, and the Middle East, where he comes face-to-face with the man responsible for Cooper's death.
