ePub Viewer

This would be an excellent ePub reader except for two major, inexcusable flaws: [1] It replaces the ePub's normal color scheme with a theme, and all of the available themes make text illegible wherever the text was meant to be white text on a colored background; [2] It doesn't in any way support bookmarking. Unfortunately, my much preferred ePub reader, "Cloud ePub Reader with Drive," offers no way to remove ads and always displays the "not secure" message below the title bar.
