"When thousands of people die in China's earthquakes, Emperor Shun Di does not know what to do as it takes days for a city to communicate the news to the Emperor. He assigns his wisest advisor, Zhang Heng, to create a device that will tell the Emperor and his court where an earthquake took place."--Jacket flap.
