The Colossus of Rhodes (The Roman Mysteries #9)
Lupus longs to travel to the Greek islands, to find his mother and fulfill his uncle's dying wish. When he and Flavia, Nubia, and Jonathan hear that freeborn children are being kidnapped, they set sail. Their mission takes them from Corinth to Rhodes, site of one of the Seven Wonders of the ancient world, where they encounter a slave-dealer known as "the Colossus"--and a deadly trap. Caroline Lawrence paints a vivid picture of the times, with a surprise around every corner.
