Chain Reaction (Mack Bolan)

FINAL PAYBACK 

When a Stony Man Farm nemesis is suspected in the death of two FBI agents, Mack Bolan gets called into action. The last time Bolan crossed paths with the shadowy criminal organization, he'd annihilated their operations in North Korea. Now the group has brokered a deal that would send weapons-grade uranium to Iran in exchange for a cache of stolen diamonds. 

An FBI task force has been working the case for months, but it appears their team is compromised. They need a free agent, someone on the outside who can find the leak and complete the mission. Joining forces with a field operative, Bolan sets off on a shattering cross-continental firefight. Bolan has no choice: he must destroy the criminal conspiracy behind the threat. Once and for all.
