Name of package is "nov", and is included in ELPA.

I proposed for doc-view to be standard, but Author Vasilij
Schneidermann <mail@vasilij.de> said that is not related to doc-view,
as EPUB files are like packaged HTML files. Author is willing to
contribute, and is Emacs contributor, so I understood.

Many digital books are in EPUB format. I got every time surprised to
find that Emacs could not read EPUB, but could read PDF and other
documents.

> Why is it called 'nov-mode'?

Maybe Vasilij can answer.
