A wakes up every day in a different body. Guest for a day, A tries to do no harm, walk through that person's life changing as little as possible. Until A meets Rhiannon. Waking up as Justin seems like any other day. Justin is kind of a slob, kind of a slacker, and not all that extraordinary. A thinks it will be just like any other day, making it to class, figuring where Justin sits at lunch, if he has an after-school job. Everything changes when A meets Justin's girlfriend Rhiannon. She is beautiful and different, and A is drawn to her.
