Books With a Letter Missing (often associated with the hashtag #MissingLetterBooks) is a popular wordplay challenge that gained massive traction on platforms like Twitter and Reddit. The concept involves taking a well-known book title and removing a single character to completely change the plot, such as 'The Old Man and the Sea' becoming 'The Old Man and the Tea' or 'Harry Potter' becoming 'Harry Otter.' This meme highlights the fragility of language and the creativity of the internet community, often resulting in hilarious plot summaries or fan-made cover art. It appeals to bibliophiles and pun lovers alike, serving as a recurring viral trend that resurfaces whenever a new community or brand joins the challenge to showcase their wit.
