Please answer the following question: I know that the answer to the question "What was a rejected project?" is in "According to a National Geographic article, the novel is so revered in Monroeville that people quote lines from it like Scripture; yet Harper Lee herself refused to attend any performances, because "she abhors anything that trades on the book's fame". To underscore this sentiment, Lee demanded that a book of recipes named Calpurnia's Cookbook not be published and sold out of the Monroe County Heritage Museum. David Lister in The Independent states that Lee's refusal to speak to reporters made them desire to interview her all the more, and her silence "makes Bob Dylan look like a media tart". Despite her discouragement, a rising number of tourists made to Monroeville a destination, hoping to see Lee's inspiration for the book, or Lee herself. Local residents call them "Mockingbird groupies", and although Lee was not reclusive, she refused publicity and interviews with an emphatic "Hell, no!"". Can you tell me what it is?
