I read this book quite a few years ago. I remember enjoying it. I think it would qualify as historic fiction and is based in the times of ancient Rome. The main character is a female warrior trying to avenge the destruction of her family and tribe.
Her name was Auriane. She was a warrior, a priestess--and a threat to the powers of ancient Rome. This breathtaking saga from acclaimed newcomer Donna Gillespie unveils a fascinating world of pagans and slaves, warriors and nobles--and the extraordinary life of a legendary woman they called The Light Bearer.
