For my part I use Foliate,
and it’s great on the PC,
I really like the epub and foliate format it makes it more great.
I leave you the name in case you did not know about this reader of Epub,
is for Linux but there is also for Android,
but it is very laborious, I leave the link if you want to try it or try.
I do not use it on Android, I only read it on the PC, it is easier for me to read it.
