I have a bad news for you, recently I was interested in how could I write a good QML/Kirigami based ebook reader and looked at all the existing Linux epub reader and each one was using a webview for the epub rendering. But they usually try to integrate better with the rest of the app and your DE so you just don't see it.

EDIT: the only epub reader I know that doesn't use a webview is Okular and the rendering using QTextDocument basic html support is horrible.

Koreader and coolreader both based on crengine and dont use webview. Koreader devs forked crengine and now seem to be in the process of merging back. https://github.com/koreader/koreader https://github.com/buggins/coolreader

I ran into a similar realization when I set out to build my own minimal RSS reader.

Your options are A) web view, B) crappy RSS reader.
