A fresh perspective on Macbeth from one of today's foremost YA writers. Three girls witness the action of Shakespeare's play firsthand - and their lives are forever changed because of it. Lady Mary is a ward of Lord and Lady Macbeth whose life is forever changed when her father, Lord Cawdor, betrays the Scottish king - and is hanged as a traitor. In an instant, Mary has lost both her father and future. Now she's trapped in a castle with a power-hungry couple who will do anything to get what they want - and are willing to crush anyone in their way. Including Mary. As the murderous events of Shakespeare's play unfold around her, Mary must struggle to survive - and do what she can to prevent more deaths. But can a lone girl save lives when a legion of Scottish lords cannot?
