This beauty will soon be in my hands, God and Amazon willing, but I thought I'd leave it with you for the Easter holiday to feast your eyes upon (better than an Easter ham). It's called Ride East! Ride West! by Anne Powers and is set during the Hundred Years' War, evidently a time when material for women's clothing was in short supply if the cover is to be believed.
Powers also wrote a historical novel called Royal Bondage, the cover of which I have not seen but the design possibilities of which will supply me with hours of pleasant speculation on the way to the beach.
