We got it back!
Well, mostly, anyway. What we did was basically combine gramcracker and nickerbocker's points together. The actual book file itself was useless, and there weren't any relevant temporary file still on disk. BUT --- there were were two relevant temporary files that had been deleted. We undeleted those using FreeUndelete that my dad installed onto a USB drive from his computer. One of them contained about the last two-thirds of the book as of August 30, and my neighbor says that that the first third probably hasn't changed much since the April 30th version.
So, my parents and she are going to stitch the back and the temp file together, and all will be well. Yay!
