Thunderdog: A Teen Spy Thriller

Can they save thousands of teens from becoming weapons of mass destruction? In Japan, sixteen-year-old Miyuki always felt like a square being pounded into a round hole. She turned her back on tradition and earned the fury of her father, who sent her off to live with strangers in a strange land. Now Miyuki is one of the Gems, a group of four talented teen girls who spy for a mysterious world-wide organization known simply as The Authority.

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.

Thunderdog is the third novel in The Gems Young Adult spy thriller series, although all books in the Gems world can be read as standalone adventures. This story has plot twists, a clash of cultures, unlikely allies, fascinating settings, with a heart-warming father-daughter story.
