While I've never tried it, it's my understanding that you can use calibre to remove the drm encryption on a purchased ebook so you can read it with something like fbreader (which, as far as I know, can't read a drm-encrusted ebook).
Calibre is also available as an appimage.

Calibre itself doesn't, but there are 3rd party DeDRM plugins available for that. Calibre also includes an ebook reader that handles most formats.
