Whoo-hoo! I improved the doggerel, and I am finished--with this editing pass anyway. Yay! Now it can go beta readers, and I can take a rest from it for a while.
Although I do want to work on the book description and jacket copy now, rather than waiting and doing a big push on production all at once. Doing the cover was a lot more enjoyable when I wasn't all burnt out on production, so I'm assuming the same will be true of doing the description and jacket copy.
I'm going to take a break (hopefully just a short one) and then get going on Trials!
