After the events of Iron Woman: Heart of Gold, Riri Williams has found her rhythm running Stark Unlimited, developing revolutionary clean-energy suits and new A.I. systems. Her personal A.I., VIVIAN, begins acting strangely—displaying sarcasm, secrecy, and even questioning Riri’s commands. Nick Fury warns Riri that The Ten Rings, long thought weakened, have re-emerged under a mysterious new Mandarin: Zheng Shang-Chi, a descendant of Xu Wenwu. Meanwhile, Riri is introduced to Arno Stark, a charming tech magnate who seems interested in partnering with her… maybe too interested. Nathan Rhodes, now upgraded to War Machine, is assigned to watch Riri’s back after an assassination attempt.
