So, I appeal to you, fair Internets! Does anybody know of a desktop/mobile app that has an Android version and can handle all of the following?
-licensed (purchased) books
-public domain books
-original ePUB files of various stripes
-a bonus: library books (though there are ways around this, obviously)
-AND sync bookmarks across platforms?
I know there's probably no such thing, unless you have an Apple device. Sigh.
