Now he’s back in New York, and unemployed—until Russian Mafia boss Peter Rusanov offers him a job wiping out the Albanian Mafia.

Because within ODIN there is General Operations, which speaks for itself; ODIN 5i, which deals with intelligence gathering; and then there is ODIN 1i, which deals in operations so sensitive not even the CIA can touch them. All three are run with an iron first by The Chief, a giant with a gigantic IQ. His top agent is Alex Mason. But when an ODIN 5i agent based at the US Embassy in Manila goes missing and his encrypted laptop disappears with him, the whole ODIN structure is put in peril.

Now, with no family and free from the military's command structure, Reece applies the lessons that he's learned in over a decade of constant warfare toward revenge.
