A ghostwriter is a professional writer who is hired to write a book, article, or other literary work on behalf of someone else. They are typically hired by busy public figures, celebrities, or business executives who do not have the time, expertise, or writing skills to create content themselves. The ghostwriter's job is to understand the vision and voice of the client and then write on their behalf, remaining anonymous throughout the process. Ghostwriters must be skilled writers and researchers who can write in a variety of styles and formats and should possess strong communication skills to maintain their clients' trust and ensure that the content reflects the client's intent and goals.
