KeyError: "There is no item named 'page_styles.css' in the archive"

Hi, this tool is very useful, thanks for working on this!

I've encountered a bug with an epub that I'm putting in. Is it a case of a malformed epub?

Thanks

Thanks for reporting @jkcchan. It could also be a compatibility issue with the EPUB format. I'm interested in testing and fixing it if you can share an example of the problematic EPUB file.

Here is an example of a EPUB file that doesn't work: https://drive.google.com/file/d/1r6ODETKs4znHCrT9ZVZe93I4HWy8SJIX/view?usp=drive_link

Thanks. Will check it soon.

Hi @jkcchan I took a look into your file.

Your epub file claims to have a page_styles.css, but in reality it doesn't.

So, when ebooklib parses it, the file reading fails.

Related code in ebooklib:

Is your book exported from Apple Books? A friend of mine told me that the ebook file exported from Apple Books has formatting issues.

Not sure if this is a common case for epub books. If yes, I might need to find a way to support this.
