What is the author's style in Falls the Shadow by Sharon Kay Penman?

The point of view of this novel is the third-person omniscient. The novel includes so many different characters and such a scope of time that the author uses multiple characters to narrate her novel. The narrating point of view changes multiple times in each chapter, presenting important events in history from the eyes of many different characters who were important to those events. The author also condenses some events into short sections in which she explains important events to the reader through the authorial voice.
