Alternate title

The book I'm choosing an alternate title for is "Keeping the Moon." I'm changing it to "Us against Them" because the book has nothing to do with keeping the moon so the title is irrelevant. I'm changing it to my title because in the book Collie gets a job as a waitress and she mentions that it's like a fight, us is her and the staff, and them is the people that they serve. It's also very hard being a waitress and dealing with the customers.
