She knows there are few people who she can turn to in this time of need, but the sisters agree to help Lydia, beginning a race against time to save Harry's life.In doing so, our intrepid sisters come face to face with a terrifying adversary whom even the toughest of the slum-dwellers are afraid of...The Red Monarch.
