And the good news is that they've requested only two things, and they were things I was going to do anyway as I wrote the chapter on Lovecraft and detective fiction. The news was both a relief and a validation.
Now to re-read a couple of stories and make notes.
Also, I'm partway through the Scrivener tutorial. They weren't kidding about it taking a couple of hours. It's detailed enough that reading tales of cosmic horror is a relief. Having said that, it's going to be exactly the right thing to help with this project. I'm glad I bought it.
My plan is to finish the edits and get the revised manuscript to the editor by 14 September.
