What is the author's style in The Virgin's Lover by Philippa Gregory?

Throughout the entire novel, the language used is an appropriate approximation for the time of Tudor England. Obviously, Philippa Gregory doesn't use all of the archaic spelling or phraseology that would be almost incomprehensible to the modern reader, but instead drops a few turns of phrases and words (like "carillon" or "burgher') that indicate the time period. In this way, the novel represents the fact that it is a modern transformation of a historical tale, since there are words, habits, customs and phrases that would almost certainly be used back then that we would find it hard to decipher now (think of some of Shakespeare's allusions).
