Backwards

Backwards by Todd Mitchell, 277 pages

As Dan commits suicide, the Rider watches and as Dan dies, the Rider finds himself pulled into Dan's body.  For the next several days, the Rider finds himself living Dan's life, but in reverse.  Every day Dan wakes up, it is the previous day.  The longer the Rider stays with him the more convinced he becomes that he is meant to change something but he isn't sure what or if the things he tries will help or hurt, especially since it requires a lot of effort to even get Dan to do what he wants.  he rider starts to become aware that they are headed toward a critical moment that could mean salvation or destruction, depending on what he chooses, and he comes closer to the knowledge of who and what he actually is.  This is a pretty amazing book.  I would give it to a wide variety of teens.
