Writing backwards

Today I wrote a synopsis for a book I haven't written yet.

I don't know what made me do it. I didn't even have a story idea before I started writing, only an image of a creepy forest. What's going on in that forest? I wondered. Something dark. Something evil.

So I sat down with my journal, imagined a problem and a hero and started writing. The synopsis has everything except a solution, but those never come easily.

Maybe this synopsis will lead to my next big project (NaNoWriMo?). We'll see!
