It's pretty good, but I found two errors:
1. You said 'It was 3463, World War 5 has been going on for 3 days.' yet Izzy says '"World war 6...'
2. 'This is a story about a little 4 year old princess named Izzy, and her struggles in life through the war. Izzy is four years old and lives with her parents in Forks.' You have already stated that she is four years old twice.
