Mark Burrows is an ‘invisible man’, a British secret agent adept at moving undetected through the most hostile environments. Summoned for one last mission, he must make contact with Charlie Ashe, his fearsome former colleague and brother-in-law. Ashe has reappeared with a new name and a terrifying new agenda in the Storm Zone, a mysterious region racked by devastating hurricanes and inhabited by cults, criminal gangs and insurgent armies. The mission will force Burrows to question his loyalties and to understand that the greatest danger lies not with his target, but with the forces that seek to control the world around him.
