calibre atomically updates the book when saving -- whatever happened to
that book was almost definitely something other than calibre. Also, no
problems were reported when saving, as you said. ;)

If you rename the *.epub to a *.zip and try opening it with an archive
utility, do you see any (legible) contents?
