Since the eBook comes in an ePUB file, you will need to have an app that is ePUB-friendly:
Apple Books or iBooks: These are native apps for Mac.
Supported Platforms: macOS, iPad OS, iOS
Download: Pre-installed on all Macs, iPads, and iPhones
Sumatra PDF Reader: With faster performance and modern features, the Sumatra PDF Reader has you covered as one of the best PDF editors and readers out there. It’s an extremely lightweight Epub reader that just works out of the box. It supports bookmarks, background color change, automatic text scaling, and much more. The best part is that it can even open large Epub files without breaking a sweat with correct indentation, tree-like chapters, and more. I would say, if you are looking for a Windows Epub reader that just works without any frills then Sumatra PDF Reader is the best pick.
Supported Platforms: Windows 11 (likely), Windows 10, Windows 8, 8.1, Windows 7, Vista. and XP

Freda: The app looks like a native Windows 10 app and makes Epubs really stand out when you read them on it. One great feature of this app is its theming capabilities which allow users to customize the look and feel of the app to make it exactly how they like it. Apart from supporting Epub, the app also supports a ton of other formats including Mobi, FB2, HTML, and TXT. The app also gives you access to more than 50,000 public domain classic books free of charge from Feedbooks, Gutenberg, and other online catalogs. If looks matter to you, do give Freda a try.

Kobo: Like Kindle, Kobo is not only an ebook reader app but a service that also allows you to buy books from its store. However, unlike Kindle, which doesn’t support Epub formats, Kobo does support both Epub and Epub 3 formats. The app brings all the usual features that we have come to expect from an Epub reader including, search, bookmarks, progress tracking, theming, and more.
Supported Platforms: Windows 11, Windows 10, Windows 8.1 (ARM, x86, x64)

Nook: If you are into books, the chance that you have never heard of Barnes and Noble is pretty slim as it is the world’s largest bookseller. Barnes and Noble mainly is a chain of offline stores, however, Amazon’s success with its Kindle platform made the offline bookseller giant launch its own online book service which is called Nook.
With Nook app, you are not only getting an app to read Epub books, but also a store to buy them, just like you do with Kobo.
