Query: An Enthralling Read

Phillipa Gregory is among the best historical fiction writers of our time.Her portrayals of Robert Dudley,Elizabeth,and the whole of Tudor court life are ingeniusly accurate (I should know,I was there),and I liked the twist on popular opinion...making Mary the good hearted,if not woefully misguided Queen; and Elizabeth aggravating,selfish,dastardly, but above all sphinxlike and clever.Decidedly one of Phillipa's best novels,a wonderfully written romp through the terrors,follies,escapades,and trials of Bloody Mary,the nine day Queen,and Gloriana.
