Why didn’t I think of that before?

I just realized that I don’t have to start my synopsis from scratch.  I already have a place to start.

My query letter includes both the “back of the book” description and a slightly longer description that has a bit more depth.  That description is where I’m going to start.  It doesn’t have the end of the story, which I need to include in the synopsis, and several major plot points are vague out of necessity.  I think that taking those places and adding details will be exactly what I need to do to get a draft of the synopsis done.

As always, I’ll keep you updated.
