Sorry if these were bad I don't really have any ideas right now. If you have an idea for a preference or imagine let me know! By the way if you didn't know I have two other books I'm writing. One is about Racetrack called The One and another is about Jack which I'm almost done with. It called The Newsie. I hope you guys check them out and thank you for reading!
