I usually try to stick with one point of view in my writing, because having more than one seems to get me all tangled up (my evidence for this is Novel #3, sitting abandoned in my file drawer). So why, in Novel #4, did I add another POV? Am I crazy???
In Novel #4, there is a bit of a conspiracy against the main character. I wanted the reader to know about it, without my main character knowing about it. (See how I'm already starting to get tangled up?) So, the second point of view sort of emerged from that idea. It's challenging, but it has strengthened some parts of my novel. Some of the benefits:
1. Bringing in another point of view has forced me to see the events in the story from a different character's perspective. In the past, I've found that focusing too much on the main character's perspective can lead to weaker secondary characters. By taking another character's perspective, it has made me think more deeply about character reactions and emotions.
2. Deciding where to bring in another point of view has made me think more about the timeline for my book and how the reader will experience the story events. Do I want events to happen sequentially? Simultaneously? How does that come across to the reader? I have to think about what each character has experienced and when, then mesh them together so that it doesn't produce a jarring effect when the novel is read. This is more difficult than I thought it would be.
Have you ever worked with multiple points of view? Any suggestions?
