Things Not Seen by Andrew Clements

It wasn't that unusual for Bobby Phillips to feel invisible now and then-like when he smiled at a super-popular girl and she seemed to look right through him. Bu what happens when this perfectly normal high school kid steps out of the shower one morning and can't see himself? It's not his imagination, and he isn't some mad-scientist type with dreams of taking over the world. Bobby doesn't try to become invisible. It just happens. The worst part is that he can't tell a soul except his mom and dad. His condition would be front-page news. They need time to figure things out. For Bobby that means no school, no friends, no life, and no choice. He's a missing person. Then he meets Alicia at the library one day. She's blind, and Bobby can't resist talking to her. Could she be the one who can help him reclaim his life? -- Dust Jacket
