Whether or not one likes Starkey, his work on the Tudors is excellent. His TV programme, the Forgotten Tudors really gave an insight into both Mary and Edward.
I can recommend Legacy by Susan Kay as a stand out novel about Elizabeth, as well as the Margaret George Elizabeth I.
I think Elizabeth was bloody brilliant and walked her own path within the constraints of her time. I also think she was an atheist, or at least an agnostic, hence she wasn't going to enquire too closely into people's beliefs as long as the outward observances were met. The Via Media was genius, balancing RCism alongside Puritanism. To an extent, the broad church that is the current Anglican communion carries on the Via Media today.
Her avoidance of marriage, whilst using her potential marriage as a bargaining chip was masterful, and she realised that had she married an English noble, all hell would have broken loose. I think she did love Leicester, but knew she couldn't have him, at least publicly.
She wasn't afraid to use the talent around her, like Burleigh and Walsingham, and I suppose had to show all the time that she had bigger balls than the men around her. She managed to control them, unlike MQoS.
I can also recommend Wolf Hall and Bring Up The Bodies by Hilary Mantel. I am just re-reading them, prior to the release of the final part of the trilogy this year. These give you the story of the divorce and Anne's time as queen and downfall.
It was the Earl of Warwick, whose claim was from George, Duke of Clarence, and whose sister was Margaret Pole, who was executed.
