A book trailer is a short video designed to promote a book, similar to a movie trailer. It typically includes visuals, music, and text to capture the essence of the story and entice potential readers. Book trailers can be shared on social media, websites, and video platforms to reach a wider audience. These trailers often highlight key themes, characters, or exciting moments from the book, aiming to create interest and excitement. Authors and publishers use book trailers as a marketing tool to engage readers and encourage them to purchase or read the book.
