I don't think I have any Google books. It is not every epub book that has the problem, but the vast majority has it.
I tried to do an epub to epub conversion on a problem book from standard ebooks. It also solved the problem.
I very often do epub to epub conversion because I prefer left align to justified. When I enter a book into Calibre I always check the alignment and do an epub to epub conversion if it is not left aligned.
OT: Link to
standard ebooks Highly recommended.
