In retaliation Iran's Supreme Ruler unleashes an ultra secret weapon - Unit 400.

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.
