Naturally, I couldn't resist working on the book some more, filling in some detail, but now I am finished! Well, sort of. At least the first draft is done. I'm going to put it away for a while and let it rest. Then I'll take it out again and work it over some more before deciding whether or not to submit it to any prospective literary agents. What a dreadful ending to the magnificent process of writing!
I stuck to my outline and discovered that writing to a plot was a lot easier than just letting the story meander along at the characters' whims. That did not mean the characters didn't throw me curves. The ending turned out to be very different from what I originally expected. I started out with three possible endings. Naturally, the actual ending was none of those, and it all happened because I could not convince the male protagonist to put down the phone!
Anyway, it was a totally fun way to spend a couple of weeks, and I think I really did learn some valuable lessons about "loosening up" a bit.
