Trivia

 * The title is a reference to the ending of the Goosebumps film, where Brent Green types "The Invisible Boy's Revenge" on the typewriter. However, the book and film seem to have no connection to each other, nor does the book have any connection to My Best Friend Is Invisible.
 * According to Brandon Dorman via his Instagram, he was assigned with creating a cover that shows an invisible boy in danger with a simple background in a school setting without any other kids present.
 * The name of the school in the book is Han Solo Middle School. A reference to the Star Wars character of the same name.
