Throughout history, kings, presidents, prime ministers, and treasure hunters have sought the fabled lost city of Shangri La. For centuries, this utopia has been relegated to fiction and lore, believed to be nothing more than a legend in the eyes of every historical expert in the world. Until an archaeologist discovers an ancient map carved into a sacred mountain in China, and is murdered because of it. Now, Sean Wyatt and his team from the International Archaeological Agency must trace his work and solve a series of clues that wind through China, and relearn this fascinating country's history that could lead to the key to opening Shambala's gates. But they aren't the only ones who seek the door to Shangri La. An old rival is chasing down the clues as well, financed by one of the Far East's most powerful underworld leaders.
