This is a short story that I wrote forever ago as a narrative for my English class. The topic was school, and I felt like everyone's story was just too happy, and we needed to include some of the bad in there as well, in order to balance it out. My story is about Connor, a sophomore who I feel many people can relate to, who's trying to rescue her little sister, Ava, from the shooter. If you're uncomfortable with these sort of topics, I would suggest leaving my profile this instant because I have a tendency to focus on the bad, while I occasionally will leave some happy moments that cause you to wonder, as you will read towards the end of this book, if you last that long.
