You can often buy the EPUB directly from the publisher's website, which ensures the author receives proper royalties.

Be cautious of sites offering "free EPUB downloads" that aren't affiliated with libraries or major retailers. These sites often host pirated content and can be a source of malware or phishing attempts.

You can purchase the ebook directly from Amazon (Kindle), Rakuten Kobo, or Barnes & Noble (Nook). Most of these platforms allow you to download the file for their respective apps.
