What is the author's style in The Wolf and the Dove by Kathleen E. Woodiwiss?

The story is written in easy-to-read English. The story is divided fairly evenly between dialogue and exposition with the author presenting a great deal of the story though this dialogue. The dialogue may prove difficult for some readers. In an apparent effort to keep the story true to the period, the dialogue consists of language that is sometimes not easily grasped. For example, Wulfgar is speaking to his father about the relationship between Wulfgar, Bolsgar and Wulfgar's brother. He says, "My brother? Never, for he became the favored one. You? Deeply, I wouldst think, for you and I were truly father and son. But you in honor to her cast me out, sent me far away to that foppish sot who took the coins you sent and gave me for care but the meanest share."
