It is the Year of the Wood Dragon, and the ingenious Mike Brink has been invited to Tokyo, Japan, to open the legendary Dragon Box. The box was constructed during one of Japan’s most tumultuous periods, when the samurai class was disbanded and the shogun lost power. In this moment of crisis, Emperor Meiji locked a priceless Imperial secret in the Dragon Box. Only two people knew how to open the box --- Meiji and the box’s sadistic constructor --- and both died without telling a soul what was inside or how to open it. Every 12 years since then, in the Year of the Dragon, the Imperial family holds a clandestine contest to open the box. Every puzzle master who has attempted to open it has died in the process. But Brink is not just any puzzle master. He may be the only person alive who can crack it.
