The Kill Chain

Seven men dead in a valley that should have been empty — and Senior Chief Warren Braddock survived long enough to learn the ambush was no accident. A thumb drive left behind by his best friend reveals a conspiracy that reaches from private arms dealers to the highest corridors of the Pentagon. Now Warren must decide how far he's willing to go to expose the men who murdered his brothers, knowing the same machine that sent his team to die can just as easily erase him.
