The Girl King
Based on history and legend this is the story of Tamar, the girl king of Georgia in 1177. Beset by invaders and enemies her father respects her as a probable leader but others don't agree. Women have a role in this culture and ruling isn't one of them. Tamar has to win respect and help and marry a man suitable for the role, but her heart is elsewhere.
A skillful blending of fact and fiction, this is an entertaining read. I suspect some of the lag is due to the blend.
