Hi guys! I'm on the final stages of self-publishing one of my manuscripts.

But I'm a bit stuck on the back cover and writing the back blurb.

I've seen so many examples I'm a bit overwhelmed and confused on what exactly I'm supposed to put.

Some books have summaries. Some have catchy little teasers. Some have short blurbs from the actual manuscript.

What do you think is best and most eye-catching/marketable?

A summary, a catchy teaser, short blurb from the book, etc?
