Telling your story in a certain point of view can make or break it. In fact, that's what broke my first book. I had six key characters that each felt equally important to me. I told the story from all points of view. Can you imagine how confusing that was? I was switching back and forth on every page and I never really got the reader inside any one character's heads with good monologue. Can an author tell a story from multiple points of view? Sure, Frank Herbert, Brian Herbert and Kevin Anderson all pull it off beautifully in the Dune series. For any of you who have ever tried to read Dune and had to put it down, point of view is probably why. While it can be done that doesn't mean you should do it. Once I realized I was no Frank Herbert I knew I had to change the way my first novel was written.
The question you have to ask yourself is, whose story is it? Among your characters, who is the most important to you? Upon asking this of myself I realized the answer was obvious. Problem was, it was still two characters. That I can deal with though. With only two main characters it's easy to switch points of view from one chapter to the next. Just remember not to do it within the chapter or you could lose the reader and jumble the story.
Now that I've had this epiphany I'm really excited about pulling that manuscript out and giving it an overhaul this year. Two bad it isn't written on my calendar's to do list until August! But that's okay. In the meantime it's percolating in my mind and becoming something richer and deeper with each passing day.
