I don't understand how paragraphs start and end in these files. Otherwise you
can try using one of the text processing tools mentioned here:

* https://www.shlomifish.org/open-source/resources/text-processing-tools/

* https://www.computerhope.com/unix/ufold.htm

* https://en.wikipedia.org/wiki/Fmt_(Unix)

* https://en.wikipedia.org/wiki/Par_(command)

Note that you may have better luck converting EPUBs (assuming they lack
https://en.wikipedia.org/wiki/Digital_rights_management ) to plaintext using
tools such as https://pandoc.org/ ,
