Good God how many people on this forum are seventeen? Are we attracting an incredibly specific demographic?
When I first started writing Fallen it was in third person. I wrote this way for around 16 chapters before I finally decided that it wasn't working out for me. As a writer I couldn't connect as easily to her, my main character, when I wasn't directly in her head. She became relatively flat and uninteresting because I focused more on what was happening to and around her, rather than what was going on inside her.
Switching to first person for that story felt so freeing. I know that that sounds counter intuitive, but it was true. When I became Her, she became real, it was as simple as that. I heard her voice in my head for the first time and her internal conflict became much more complex
Her sassiness levels also went off the charts XD I'm still not sure why, but I kept in. To me it made her feel that much more legitamate, the fact that her character emerged seemingly out of nowhere.
