Whenever I write a new PB I always also draft a little blurb to go along with the story. I do this even when my mansucripts are very, very rough because it helps me focus on my main idea. I am easily distracted and will often - SQUIRREL! Oh yea, and just like the main story, my blurb gets edited over and over again.
Since drafting blurbs (and pitches and synopsis) is one of my favorite author "hacks" for creating a strong MS, I was thrilled to come across the following blog post by author Stef Gemmill. She brilliantly explains the difference between these itty bitty - but oh so important - word piles.
