Anthansia

Anthansia the favoured daughter of Hypatia, Empress of Rome went missing at a young age, and despite the best efforts of the Emperor and Empress she was never found. Missing for 10 years, Anthansia was taken in by a slave family who found her lost in the forest babbling about some 'made up life'. Convinced by her adopted family she was no more than a slave girl Anthansia accepted her new life and went on to become a Gladiator for the Commander Adrasto in the new arena the Emperor spent 10 years building in memorial to his lost daughter.
It's in that very arena Anthansia finds the truth about her life, finds out the truth about her family. She is the Princess, heir to the throne. The Commander's son Cato helps her to unravel the truth and takes her back to her family...
But can Anthansia adapt to life within the royal family? Can she deal with the traitory within her own castle walls? Can she watch her own back long enough to stay alive and take the throne?
With the help of a Guard, a cousin and a couple of dragons...
Well only time will tell.
