As we've been saying all along, the files are encrypted. You have an epub with DRM in it. And it appears to be missing some files. Or, you have a Kobo ePub that has DRM. Their DRM is different from the more common Adobe DRM, and does not include some of the files I mentioned. Plus some files that are encrypted as part of the Adobe DRM are not encrypted by the Kobo DRM.

No matter what, I don't think we can help more. You probably need to go back to the source for the book and ask for a non-DRM protected version. Or download it properly using the appropriate application and use the DRM removal tools from Apprentice Alf.

Okay...kind of frustrating...I'll go and see if I can get a non-DRM version (doubtful). I already have Apprentice Alf's tool installed and it didn't remove this DRM...

Since the file is actually DRMed it should be fine to post to mobileread. So re-attach it and I will see if I can get calibre to recognize the DRM so that when you try to view/convert it, you at least get a nice error message telling you the file is DRMed.

Thanks!

Interestingly that file seems to have been created/edited with Sigil and then post-processed by some tool to encrypt all the HTML files and then base64 encode them. I can see no indication in any of the metadata files that the file is DRMed, so detecting it in calibre is problematic.

These are the folders just zipped up that are used in the proprietary app.

Would it be possible to check that if content.opf and/or toc.ncx start with "<?xml version="1.0" encoding="utf-8" ?>" and the HTML text files do not as an indication that the epub uses Deseret's encryption? Or even that the first character of the html text files is not "<"?

Looking at those files, they look like an unpacked epub file. Change the extension to epub from zip and you get an epub that has issues with the contents of the text files. Comparing the .epub you originally posted to the .zip, they are identical.

The content.opf file does start with "<?xml version="1.0" encoding="utf-8" ?>"

The html files (which are xhtml files) when opened with notepad just show random text, like this:

Does that help?

The message was more to Kovid's attention. It's so easy when I don't have to program the detection myself.

What might help is - if you could confirm you purchased this book from Deseret, and that you can read it with the Deseret reader?

And if you didn't buy it from Deseret, then where you did buy it? Different publishers use different encryption algorithms and they are constantly inventing new ones to thwart piracy. So if you paid Amazon for it you should be able to read it on your Kindle, similarly for B&N and your Nook etc.

I did buy it from Deseret book and I can read it on Deseret Bookshelf (their app). I was hoping to be able to listen to it via Moon Reader+, thus the desire to create an epub that can be read in Calibre.

That's not a sufficiently robust check. There can be buggy HTML files that contain ggarbage content, doesn't mean the epub is DRMed.

I suggest you ask Deseret if they provide a means to listen to the text - or maybe they have the series in MP3. Amazon has Hearts of Children CDs.

Essentially what Moon Reader or any other epub listening app does is to 'extract' the epub content to plain text, and then feed that into a Text To Speech (TTS) engine; some operating systems have 'built-in' TTS engines.

Because your epub is encrypted, programs like Moonreader can't 'extract' the plain text any more than calibre can.

There's a limit to the extent DRM removal can be discussed at MR. I fear we may be close to that limit - see item 8 in the Posting Guidelines.

Sigh - see what I wrote in here about Audiobooks
