The main character's name in Every Day, goes by the name, A. He doesn't really know how old he is, but he supposes that he is about the same age as the bodies of the people that he jumps into on a daily basis. For as long as he's been alive (and he doesn't remember where he came from) at midnight every night he is compelled into the body of another person. He can't control it at all. When he is in their bodies he has access to all of their knowledge, but they also have access to his abilities and intelligence as well. This works to the advantage of the host body, most times.
