I've been stuck in a mess of my own making in the middle of the Alexa book. I introduced a character and then watched my plot run away in a direction I never intended.
Five chapters into that and I could see that it just wasn't working.
I left it alone for a week, examining the situation, trying to figure out where I went wrong and how to get the book back on track.
Two nights ago, I went to see Bourne Ultimatum with friends and halfway through the movie, I figured it out.
It was a little hard to concentrate on the movie and replot/reposition my characters but, like many writers I know, once an idea took hold and I could feel that it was right, I couldn't let it go.
Unfortunately, I have to scrap five chapters but it's worth it just to get it right!
