[QUOTE=kazbates;1508369 There is a good 1/2 inch border on all sides and it is not fully justified..[/QUOTE]
often the case with Adobe Digitial Editions ( ADE for short) very easy to fix. those books have an extra, hideous stylesheet file. see e.g. this thread for how to remove it / negate it's effects.

justification is v easy in all cases. you look at the stylesheet file & look for (find) anything that says
text-align: followed by one of these words
left, right, centre, justify. replace
left with
justify & you should be done.
you may also find that simply running the book through calibre i.e. convert it
from epub
to epub will so an automated repair of page settings & take out your wide margins.
