Celebrity book clubs are reading groups led by famous individuals who share their favorite books with fans. These clubs often select a monthly book, encouraging followers to read along and discuss the chosen title. Many celebrities use social media platforms to announce selections and engage with readers, creating a sense of community. Popular examples of celebrity book clubs include Oprah Winfrey's Book Club and Reese Witherspoon's Hello Sunshine Book Club. These clubs often highlight diverse authors and genres, helping to promote literature and increase visibility for lesser-known works. They can also influence book sales and trends in the publishing industry.
