In Book Two of THE RAD TRILOGY, the celestial messenger "RAD" has traded places with his earthly half-brother Gemini in order to save a small circus, and the world, from conversion to the ways of the Evil One. While learning what it's like to be human - and struggling along without his superpowers - RAD must take on the Evil One and right his wrongs. Will an ancient scroll revealing classic moves in the game of chess be enough to prepare RAD for the ultimate match with the Evil One?
