Comments about calibre as an Alternative to Apple Books
Calibre is a great program for management and ebook conversion but its built-in reader is crappy and has no animations. not intuitive. bad gui. great program, bad reader. Moonreader for android is way better, but I want something with similar functionality to either moonreader or apple books and calibre can't display as well.
It has all the features of iBooks. Fonts size change, highlighting, bookmarking, dissection of Chapters.

Most users think calibre is a great Apple Books alternative.

It let's me read the epub files, however, it has twitches sometimes, not switching the pages right away.
