Hi folks!

I've got an email from a nice lady who is trying to send me a bunch of editing notes on one of my books. She uses Calibre to make the highlights, and has sent me the book file in .azw3 format.
I can't find the highlights anywhere, and as far as I can tell, it's not possible to send them that way.
Is that correct?

If so, is there any way she can send me a copy of the book with her notes/highlights attached? I read in the Calibre 5.0 documentation that "Highlights are stored directly in the EPUB file for easy sharing" - does this mean she could convert the file to EPUB and that would maintain the highlights for me? I've tested this myself, highlighting a chunk, then re-converting the file to EPUB, deleting the original and re-importing the new version, but the test highlights I made are still missing...
Is this possible at all?
And if so, what am I doing wrong?

Thanks in advance, folks!

Tony
