I was thinking along the lines of if you already had them downloaded and wanted to switch off to something else

My Kobo e-reader is pretty nice and takes any ol e-pub file just fine. And Calibre, a third party software for managing ebooks, has a plugin to crack Kindle files. Just sayin

I’ve got a kobo Clara HD with plenty of pirated books on it, works pretty well, would recommend

Massage them…?
