Immersed in History – 15th Century

This is going to be fun. I just finished reading a book by Phillippa Gregory, a well known and prolific writer of history novels. My choice was The Lady of the Rivers. This was her first book. in her series The Plantagenet and Tudor Novels. I could hardly put it down. Now I plan to go straight on and read The Red Queen, the 2nd novel in the series. 15th century i English history. Who would have thought this would ever interest me?
