Sixth grade is just out of this world...

Susan Simmons can tell that her new substitute teacher is really weird. But she doesn't know how weird until she catches him peeling off his face -- and she realizes that "Mr. Smith" is really an alien!

At first no one will believe her -- except Peter Thompson, the class brain. When Peter and Susan discover Mr. Smith's horrible plans for their classmates, they know they have to act fast. Only they can get rid of their extra-terrestrial visitor -- and save the rest of the sixth grade class from a fate worse than math tests!

      I recommend this book to any sci-fi lovers out there. Coville did a great job explaining a lot of things. SPOILERSS:For example, he did a good job explaining how the teacher looks like!
