Larius and Kyra become wards of Rome when their father, a Parthian nobleman, is killed in battle. In order to save his sister from slavery and possibly worse, Larius is caught up in political intrigue when he agrees to become a spy for his would-be benefactor, the Roman procurator, Publius. From this point on things become more complicated for both Kyra and Larius. As their lives intertwine with history, they experience the good and the bad. Most of all, they survive, heroic and strong.
