Benjamin and his best friend Andy are different from normal. They love being able to read each other's minds and use telekinesis to play tricks on other kids. In fact, they are getting all set to spend their entire summer doing just that when Benjamin's mirror starts talking. Suddenly, Benjamin's looking at eight weeks of summer school someplace which can only be reached by a teleporter inside the ugly picture in his hallway.
And that's the most normal thing he does all summer.
