What is the author's style in Ella Enchanted by Gail Carson Levine?

"Ella Enchanted" is told by Ella herself, from a first-person viewpoint. Ella, as the narrator, sometimes seems to know what is coming in the future, but in general she indicates that she does not know what the future holds. Ella's point of view is greatly expanded by her magic fairy book. This book can show her other people's recent diary entries, letters people have written, maps of people's progress in traveling, and illustrations of what certain people are doing at that moment. This makes it possible for the narrative to include events and details that are far removed from the main action. This really helps the story move along, since it consists only of what Ella observes, and since she is often shut away as a captive for long periods of time.
