I loved this book. I knew some about Matilda and Mary Tudor, but the other women were pretty hazy. Castor did a great job bringing them to life, dragging all their dramatic and powerful exploits out into the light of day. Eleanor of Aquitaine might be my favorite, although the idea of Matilda racing across the landscape, battling with King Stephen, is awfully compelling. Margaret of Anjou was also pretty cool--really surprising--but I was a little worn out as it all wound down.
This is a pretty crummy review, not at all worthy of the book. I guess I'm just sleepy. Anyway, if you're into English history and love learning about the strong women in England's past (pre-Elizabeth), this is a great choice for you. It really helps if you have some knowledge about major things like the Norman invasion and the War of the Roses.
