Well, I spent the whole weekend rereading The Mars Imperative from end to end, making hundreds of minuscule edits. But it's done, and should be ready to go (barring any last-minute changes by the editor).
I also saw a couple of cover mockups this morning. I chose one of the two concepts, and now the artist and I are going back and forth over some of the details. But it shouldn't take much longer to settle on the final look. I know this will sound silly, but I love the font she chose for the title and author name. It has just the right feel for the title. I'll post the final cover image once I get it.
P.S. With the edits done and the cover nearly done, this is starting to feel real! 8^}
