The Tower of London: Palace. Fortress. Prison. In February 1554, Lady Jane Grey, queen for just nine days is sentenced to a traitor's death at the age of sixteen. Many say she does not deserve to die, but the Bloody Tower will have no mercy on her. Young Tilly Middleton also lives in the castle. As she watches the plots and politics of the court unfolding she records her thoughts and fears in her diary. Through her eyes, the reader is transported back to these turbulent times, and waits with bated breath, along with Tilly, as she looks for a chance to deliver a very important letter -- one that could change the course of history and the fate of Lady Jane Grey.
