I remember reading this book in the late 80's and I think it was the 2nd book in a series. The only details I really remember of it are: 1. The boy had to fake his death in the beginning (involving a bus) and move to another town. 2. He had special powers and could turn invisible 3. He kept having premonitions about upcoming events. 4. One of the premonitions involved lightning during a little league baseball game. I also think the planet he came from was something like Altair or another "A" name.
