Things Not Seen is by Andrew Clements. When fifteen-year-old Bobby wakes up and discovers he is invisible, his whole life is thrown into turmoil. He doesn't know how to become visible again, his parents may face jail because he's gone "missing", and he struggles with a budding relationship with a blind girl he met at the library. A wonderful tale! It is touching and funny and a lot of good science fiction fun.
