The Diary of Lady Jane Grey

DISCLAIMER: THIS ISN'T FROM THE ACTUAL DIARY (assuming she had one) OF LADY JANE GREY!
Lady Jane Grey was queen of England after Edward VI died, however, her reign was short. VERY short, as Queen Mary I (you may know her as Bloody Mary), plotted to take back her throne.
With a religion 'war'(so to speak), a powerful woman plotting against her, and citizens feeling uneasy about her place in the monarchy, how will this inexperienced Queen survive her reign?
