A book reviewer is someone who reads and evaluates books, providing their opinions and insights to help others decide whether to read them. They often write reviews for various platforms, including websites, magazines, and social media. Their assessments typically cover aspects like the plot, characters, writing style, and overall impact of the book. Book reviewers can be professionals, such as literary critics, or amateurs who share their thoughts online. They may focus on specific genres, such as fiction, non-fiction, or young adult literature, and their reviews can influence readers' choices and even a book's success in the market.
