Tim Storm gives some good examples of the ever-difficult back cover blurb for fiction and deconstructs them.
I heard someone say once, write 5-10 different version of the same blurb, then narrow down from there. I agree. Narrow down to 3-4 and share with people you know who read. Ask them, “Which one would make you want to pick up this book?”
I have never done this step early, but I do agree that, just like writing your elevator pitch early, it will help you focus as you write. Or when you’re editing, it will help you know what you can cut.
The back-cover synopsis lays out the book’s premise and piques reader interest. Here’s how and why you should write one early and often.

Where Publishing Dreams Become Reality
Your book blurb is very important, not as important as the cover but a close second.
I was at the Sterling North Book Festival this weekend selling my wares and after people stared at my covers for a few seconds, they picked up a book and read the back, even if I was talking to them.
Claude and Mathew Kadish give us some ideas for the piece on the back of your book, or the description for you ebook online (same thing). I agree with all the suggestions made (though I think 5 paragraphs is too long – 3, maybe 4 is about right) and I like the person’s suggestion in the comment section – go to a bookstore or library, look online at the book descriptions/blurbs on the back of the book for best-selling titles in your genre and take notes. Imitation is the best form of flattery!
I also think the open lines need to hook the reader, as well. Think – a jazzed version of your ‘elevator speech’ about your book.
Here is their list:
