I saw a news article on the internet about a giant mound of tires in South Carolina that apparently sprawl across the landscape (paraphrased from the news article). From what little I read, you don’t realize just how big the pile is from the ground. However, it IS visible from outer space. Can you imagine? Talk about seeing things from a different perspective!
As writers, when we talk about Point Of View, we’re mainly talking about from a specific characters POV. We give only information that character knows at that point in time. If you think about that pile of tires, we don’t see the sum total while standing on the ground. But flying above it, you see the whole picture.
This also applies to a book. At the beginning of a story, the reader sees only one small piece, one frame of the characters lives. By the end of the book, they know all about the character’s secrets, desires, flaws, goals, obstacles and HEA.
By the end of the book they’re the person sitting on the space station looking down and seeing that humongous pile of tires. Neat, huh?
