This fictional adventure book leads readers to follow the journey of a former U.S. Army captain, Robert Gray. A scientific organization wanted Gray to traverse the unforgiving terrain of Gobi Desert to seek the hidden city of Sungan, where the reclusive race of Wusun supposedly lived. In his expedition, Gray has to race against other teams from China and Britain who are trying to find the people of Wusun for their own nefarious needs.
