Fourteen year old Cadmus has been scholar Tulluss slave since he was a baby; his master is the only family he knows. But when Tullus disappears and a taciturn slave called Tog, formerly a British princess, arrives with a secret message, Cadmuss life is turned upside down. The pair follow a trail that leads to Emperor Nero himself, and his crazed determination to possess the Golden Fleece of Greek mythology. This madcap quest will push Cadmus to the edge of the Roman Empire, and reveal unexpected truths about his past.
