Hiring a publicist is a great option since they offer insight and experience into the marketing side of book publishing. It keeps you focused on being the writer and author of the book and having someone focus on the rest of the work load. A publicist will help you reach the appropriate media coverage for you and your book. Most often, publicists have experience and knowledge to promote your book in avenues that will advance sales while you focus on writing and promoting the book with your friends and family.
