Your “book blurb” is what goes on the back cover and describes your story on sales sites. It needs to capture the essence of your story in such a way that it grabs potential readers’ attention hard enough that they can’t wait to buy your book. These are not easy to write. Most authors have less trouble writing the entire book. Similar to an “elevator pitch”, but a little longer, you can embrace more detail. Don’t say too much, however, and by all means leave them wondering how it turns out! If you’re really stuck writing one, read a few online or in a bookstore to get ideas and also sense what works and what doesn’t.
