A book blurb (also called a “back-cover blurb” or a “book description”) is a short description of the book's main character and conflict, usually between 100 and 200 words, that traditionally is included on the inside cover or on the back of a book.
What do you say on the back of a book cover?
If you are a novelist, your back cover should provide a short summary of what your book is about. Write only a paragraph or two, and include the hooks—the story's most engaging plot points. If you queried agents or editors at any point, you might be able to start with the hook from your query letter.
What is a book blurb called?
Often referred to as a “book description,” a blurb is a short piece, around 150 words, to promote your novel. You find blurbs on the back cover of paperbacks, the inside back cover of a hardback, and on book description pages in online stores. Think of this as the elevator pitch of your book.
