What is the author's style in The Golden Fool by Robin Hobb?

The language of Golden Fool is formal, but readable to the modern reader. It is not written in a formal, time period language of medieval times. The characters speak in a formal way, similar to modern speech. This helps with understanding the storyline, since it is quite complicated. The meaning of the formal language is that the characters must speak this way because many of them are servants to royals. Also, many of them are royals and speak in a highly formal way.
