Try ReadEra [play.google.com/store/apps/details?id=org.readera], I haven’t found a format it can’t read, it has a fantastic UI that makes it really easy to find stuff, it will save your place and also has bookmarks to save specific pages and it’s free version has zero ads, literally none at all, which is absolutely insane for how feature rich it is.
So make sure you buy premium too and support the Dev, even though it doesn’t offer a hell of a lot more it’s just such a fantastic app you’ll feel guilty not paying the tiny bit for the premium version.
