"Out of sight, out of mind" takes on a twisted new meaning in this horrific adventure in one of the-bestselling children's series of all time.
On Max's birthday, he finds a kind of magic mirror in the attic. It can make him invisible. So Max and his friends start playing "now you see me, now you don't." Until Max realizes that he's losing control. Staying invisible a little too long. Having a harder and harder time coming back.
Getting invisible is turning into a very dangerous game. The next time Max gets invisible, will it be... forever?
