An eminent Iranian scientist has made a startling breakthrough in nuclear weapons research, but he can?t stand the thought of his regime owning the bomb. He would run if he could, but if he does, his family dies. He is desperate; he doesn?t know what to do. It is up to Sean Dillon and the rest of the small band known as the Prime Minister?s private army to think of a plan. Most particularly, it is up to their newest member, an intelligence captain and Afghan war hero named Sara Gideon, who thinks there just might be a way to pull it off. But plans have a way of encountering the unexpected. And as the operation spins out, from Paris and Syria to Iran and the Saudi Arabian desert, there is very much that is unexpected indeed. And much blood that will be spilled.
