In her lauded biography England’s Mistress, Kate Williams painted a vivid and intimate portrait of Emma Hamilton, the lover of English national hero Lord Horatio Nelson. Now, with the same keen insight and gift for telling detail, Williams provides a gripping account of Queen Victoria’s rise to the throne and her early years in power—as well as the tragic, little-known story of the princess whose demise made it all possible.    Toward the end of the eighteenth century, monarchies across Europe found themselves in crisis. With mad King George III and his delinquent offspring tarnishing the realm, the English pinned their hopes on the only legitimate heir to the throne: the lovely and prudent Princess Charlotte, daughter of the Prince of Wales and granddaughter of the king.
