I wouldn't recommend using the   to attach the last word in ebooks.
Many worse issues would occur, especially at large font sizes + small screens.

Are you working on books in a specific language that has these rules?
If it's actual language conventions,
perhaps there can be an argument made for using   in rare cases. (In Polish, single-letter words like 'z' or 'w' at the end of a line = wrong.)
... but if it's "just for looks"... no, I wouldn't use non-breaking spaces in that way.
Side Note: In CSS4, there's an issue noted for "Last Line Minimum Length", but nothing came out of it so far:
