It was about a kid who made himself photosynthetic. And that's really the only thing I remember about the book.
There was a good quote in the book. Something along the lines of "if I told you I could whisper in the ear of somebody in China, would you think I was crazy? With a phone, I can whisper in the ear of somebody in China."
I probably butchered that quote, but you get the point...
If you know what the name of that book is, please tell me.
