The Invisible Book of Invisibility

The Invisible Book of Invisibility was a textbook about the power of invisibility. As the manager of Flourish and Blotts told Harry Potter in 1993, at some point before 1993, Flourish and Blotts ordered a stock of the book, only to have them disappear; no one was able to find them.
