Dear Jgoguen,
I bought the aura last Saturday, and I've been syncing it with the HD (it is supposed to be a backup, and a lightweight alternative for commuting). I was surprised that one book (among 1871) remained an epub in the aura, while it converted to kepub in the HD. I have also two other Project Gutenberg books that don't convert for both readers though I've tried to improve them with Sigil (one html file per chapter, and a TOC).
Here is the error log
Spoiler:

I attach the document.
I have the latest versions of everything.
I can read it fine as an epub, this is just an information, not a request for correction.
