What is the author's style in The Princess Bride by Rob Reiner?

The story changes time and point of view. The story of The Princess Bride is told from the point of view of the omniscient narrator. The narrator is someone other than William Goldman or S. Morgenstern. The narrator carries the reader between events moving back and forth with ease. The reader views the action as if watching over the characters' shoulders without being involved. Although the reader feels close to the action, the reader does not know the thoughts of the characters unless the narrator reveals them. The reader knows only what the narrator chooses to report; however, the reader does not feel detached from the action of the story. The narrator uses warm, engaging narration that brings the reader into the story.

Because of the closeness the reader experiences with the story, the reader is often abruptly shaken when William Goldman interrupts. Goldman often interjects himself into the tale to discuss his personal feelings or to mention that Morgenstern included a large section of material Goldman edited out. The reader must disengage from the story and readjust to receive what Goldman has to report. Goldman usually transitions the reader neatly back into the story. However, there are a few places where the reader must re-read several times to figure out where Goldman has stopped speaking and the narrator has returned.
