Newton, A. I.: - A. I. Newton is the pen name for Michael Teitelbaum, who has written numerous books for children. He always wanted to travel into space, visit another planet, and meet an alien. When that didn't work out, he decided to do the next best thing-write stories about them! The Alien Next Door series gives him a chance to imagine what it's like to hang out with one. And you can do the same-unless you're lucky enough to live next door to a real-life alien!
