Second draft is done

Finally.  Man, that took forever.  The second draft of Mars actually took longer than the first.

This draft is 73,000+ words long, so I've added about 15,000 words.  I expected to add a few thousand--I almost always add material during revision--but not quite that much.

Next up, I guess, is the Kindle edit.  Once that's done, I'll send Mars off for beta reading, and then I'll get back to Venus and Mercury.
