Thunderdog

Can they save thousands of teens from becoming weapons of mass destruction? When a new energy drink called Thunderdog causes a rash of violence at their high-school, Miyuki and the Gems are sent to Japan to find out why. The visit forces Miyuki to see her father, now a senior executive of the company that produces Thunderdog. As Miyuki struggles with family, the Gems uncover a dark trail of conspiracy, bigotry, and a diabolical plan that would see most of the great cities of the world burn.
