Its an amazing app with so much capability once you figure out how to get ePubs on it. I put them on Dropbox first then went into the download section in the app, selected Dropbox, connected it to Dropbox and downloaded each ePub one by one. Once you get the iTunes transfers working itll be a fantastic app; a perfect replacement for Stanza~!
