More about the book

Trouble has a way of seeking out Nicolas Calva, and it's not likely to leave him alone any time soon. With Caesar's magic bulla, the Malice of Mars, and the possibility of a Jupiter Stone in play, all the powers of Rome are circling Nic. He'll have to maneuver his way through scheming government officials and reawakened magical beasts to save the Empire. Can he manage to keep his friends and family safe, claim his own freedom once and for all, and rescue the Empire -- before the magic gets the better of him?
