My favorite book growing up was one starring Grover from the Sesame Street called "There's a Monster at the End of This Book". My grandmother would always read it to me. The book was about Grover trying everything he could to keep the reader from turning the pages because he was scared of the monster at the end of the book. The only problem was that the last page was missing where the book reveals that Grover is the monster, so for years I was scared that the monster was on the loose and was going to get me.
