When the leader of North Korea is catastrophically injured his incapacitation inadvertently
triggers a dead-man's switch activating an army of sleeper agents in South Korea and
precipitating a struggle for succession. Jack Ryan Jr. is in Seoul to interview a potential
addition to the Campus. But his benign trip takes a deadly turn when a wave of violence
perpetrated by North Korean operatives grips South Korea's capital. A mysterious voice from
North Korea offers Jack a way to stop the peninsula's rush to war but her price may be more
than he can afford to pay.
