When writing a work of fiction there are a number of ways to approach point of view. At a fundamental level, choosing a point of view is about deciding what information you’re going to make available to the reader, and how that information is going to be presented.
A story written from the perspective of a single person often feels more intimate, because the reader has direct, unfiltered access to the thoughts, emotions, and perceptions of a single character. But there are other kinds of stories that require a little more authorial involvement. In these situations, writers may reach for a style of narration that’s more omniscient or removed from the story and characters.
