Are you converting Kindle books to ePub in Calibre? Remember this is a rare happening to only about 20 books out of 2,000+ over the years. I used iMazing to import the ePub into Books.app on my iPad Mini 5 and there isn't the problem. This tells me that as it was suggested above, the problem has to do with MapleRead's rendering.

Thanks for the tip re the book views, I had never seen that before. I can’t reproduce this bug using Classic Book, but I did not test it a lot.

I use native epubs, with no conversion. One thing I have noticed is that MapleRead sometimes screws up the rendering when you rotate the IPad and switch between portrait and landscape.

Well, I've always used MR in portrait so I doubt that would be the cause. Anyway since it is so infrequent, I'll just use Books.app to read any more that I find have the problem.

You're welcome on the book views. Tried them all and decided I like the Classic Book the best.

OK, Let's see if this worked.

That scrambled book looks fine in both Calibre's viewer and on my Kobo Forma.
In the Calibre editor, everything looks ok to me (I only dabble). There's nothing odd going on with the classes/styles in there that I can see and they look fairly simple.

Again, I'd guess it's some kind of odd issue with MapleRead. JSWolf's suggestion of something to do with the left margin in the viewer sounds good. But, why it would show up only occasionally, I don't know.

EDIT: Let me qualify the above. In the editor, by "ok," I mean that I don't see anything obvious that would shift your pages like you're seeing. But, there are some issue with the files. Running "Check Books" in the editor give a lot of invalid ids. But, I run across that a lot. The more problematic stuff is from running the epubCheck plugin. There are quite a few things in there that it doesn't like, but I'd guess most of them are caused by the same things:

- classes in the <html xmlns="http://www.w3.org/1999/xhtml" class="calibre"> line near the top of each file
- types of things outside of paragraphs or divisions.

Even though it looks trivial, probably the most troublesome thing is that whoever formatted this, wrapped most of the body of the text in elements:


...
...
...


My understanding is that those bold elements need to be inside containers, or preferably in the classes/styles (add "font-weight: bold;" to all appropriate classes on the stylesheet). Maybe that has something to do with the issue. But if so, it's not obvious to me.

Dave, since the ePub is conversion from Kindle book, could some or most of those errors be related to stuff that was in the Kindle book but is not needed in an ePub book? Oh, I'm restricted to Calibre 3.48 do to my iMac being maxed out at MacOS 10.13.6 High Sierra.

The epub had some issues with some renderers. I went through and did a quick cleanup including removing those naked and <a> tags and doing a quick basic cleanup on the CSS. This cleared up the issues I saw.

I've attached the modified file to this message and would be interested in seeing if it still exhibits the issue you were seeing.

Thanks. However since this is the first time I've used this plugin, will it unscramble it? If not, how do I get the cleaned up ePub so I can put it in Calibre?

Basically, I just wanted you to view the epub to see if it still exhibited the problem. There is no way to unscramble it.

Because this is a Kindle Unlimited eBook, I was able to get a copy. After looking at this, it's clear the author has no idea how to create an eBook. He used some sort of word processor, took that output, and converted it with Calibre and did zero error checking. Amazon is also to blame for not having any sort of error checking to self-published eBooks. Even for free, I would not want to have to clean up the error riddled code.

The author has a Facebook page. I suggest you contact him and let him know that his eBooks are riddled with errors.

I'm surprised that, at a minimum, Amazon doesn't require a clean run of epubCheck for everything on their store. It reports so many errors with this book that I gave up trying to figure them out. I also assumed the errors were causing each other. For instance, the naked <b...> elements wrapping everything might have caused the errors with the paragraphs (<p...>).

Ah, that explains why it has been so rare a happening. I just went back and checked the 10 books I have by him and it is only the last 3 that have the problem so he must have changed something. However, I don't do FaceBook so I won't be able to contact him.

Edit: I went ahead and tried the FB link and was lucky to see his email address without having to login to FB so I'll drop him a line.

Let us know what the author has to say. Thanks.

Well, he responded with this information:

"Amazon used to request I upload the .mobi file, but now they want .epub. I think they then still convert it to .mobi. I suspect you going back to .epub is one conversion too many somehow."

He sent me the ePub version of his books that had the problem so I deleted the versions in MapleRead SE and loaded the new ones. All three books are fine. Thus the problem is apparently Amazon.

Now if only Amazon would let the buyer choose ePub or Mobi when they buy a book; better yet get rid of Mobi altogether and just use ePub for Kindle books.

Please load the ePub in the Calibre editor and using epubcheck, check for errors. I'm curious what the ePub is like.

Unfortunately, I can't as I'm limited to Calibre 3.48 since my iMac is limited to MacOS 10.13.6 High Sierra. When I tried to install the plug-in, I was told a Calibre upgrade was required.
