I don't get any "huge spaces" between words myself, Purple Lady. Looks like you disabled hyphenation? Try switching it on -- hyphenation works pretty nicely (though by no means flawlessly) in Moon+ Pro.
The spacing between words might especially become an issue on a tiny mobile-phone screen, or if someone uses
huge fonts... but for me on the 2013 Nexus 7 screen, that is no problem. As shown in the
Moon+ screenshots I posted to another thread, books in Moon+ Pro look really fabulous in immersive mode on the 2013 Nexus 7.
As to the troublesome books you mention... the first really isn't a book, as you say. Converting a newsfeed to EPUB is likely to result in trouble of some sort or another, I'm afraid. Calibre is superb software, but its conversion capabilities still leave a lot to be desired in some workflows. Calibre is particularly awful for converting PDF to EPUB -- the result is practically unreadable. Of course, it doesn't make sense to be converting PDF to EPUB,
anyway... But, in those rare instances you just need to do it, I have found it's better to launch my ancient, defunct Mobipocket Reader on my Windows PC, and perform the PDF to EPUB conversion there -- the result is still
awful, but incomparably better than the same conversion when performed in Calibre.
