In Rings of Fire, former Joint Special Operations Command (JSOC) sniper Patrick Featherstone has been hired as the Head Security Consultant for the Tokyo Olympics based on his success in thwarting a plot to foment a nuclear war on the Korean Peninsula. He joins up with his old friends from Sea of Fire: Tyler Kang, another former JSOC sniper, and Jung-hee Choy, former North Korean computer hacker. They are joined by the young and beautiful FBI agent Kirsten Beck, and together they frantically try to decipher a series of messages that have been sent to Patrick just before a series of terrorist attacks, which they are sure will culminate in a cataclysm during the awards ceremony on the final day of the Tokyo Games.
