When I write a synopsis, I start out by writing chapter abstracts. Basically, I take each chapter and write a 1-3 line blurb about what happens in that chapter. Then, I combine them. I take out the chapter headings and mash all the blurbs together. And I have a rough draft synopsis.
I go through, clean it up, edit things out, reword to make it more exciting/more cohesive/just plain better. I add or subtract depending on the length I'm going for, and I beef up the most important plot points.
And I'm usually left with a pretty decent synopsis.
How do you go about writing these annoying little necessities? :)
**Also!!! I've donated copies of my new picture book, A Magical World, and Homework Helpers: Essays and Term Papers for the tornado disaster relief auction site All 4 Alabama. A Magical World goes up at 1 CST today. Please come over and check it out. It's for a great cause and there are tons of awesome things to bid on!!**
