A: EPub is for Apple Books, Kobo, and Nook. MOBI is for older Kindles (new Kindles also read EPub via the Send to Kindle feature). VK often offers both, but both are equally illegal.
An interactive EPUB 3 ebook could embed a button that, when tapped, generates a VK invite link to a private reading group or live author Q&A session. The invitation would include a snippet from the book, a discussion question, and a one-click join link to a VK event.

VK is not a dedicated e-book retailer like Amazon or Kobo. When you download an EPub file from a random user's post, you are trusting that user completely. Hackers often hide malicious scripts inside file archives. While pure EPub files rarely contain viruses, many uploaders compress the EPub inside a .zip , .rar , or .exe file. Clicking on a fake .exe file disguised as The Invitation can install keyloggers, ransomware, or crypto-miners on your device. A: EPub is for Apple Books, Kobo, and Nook
