The "blow everything away" I was suggesting was a factory reset plus complete removal of the desktop app and data from your PC. Hopefully that will remove the source of the phantom book. If that doesn't fix things, then the only thing left is a faulty device. Maybe the internal memory is corrupt or damaged.
I'm not sure what I was doing wrong the first time, but I tried again and this time it worked. However, there was no change in the behavior.
I unistalled Kobo Desktop and reset my reader again but the book is still there. However, on a whim, I stopped the sync immediately after registering the reader and there was no phantom book; it appeared that everything was normal. It was only after completing the sync that the book showed up. Maybe the problem is somehow on Kobo's end? I don't know how it could be as the book was originally never associated with them in any way.
