Yes, some books, Jewish and secular alike, are always advertised as being full of “surprising” twists that’ll leave you at the edge of your seat. They leave me more confused and wondering if this is even the same story or not.
One thing that more people ought to try is self-publishing. That way, you don’t have an editor, Jewish or not, who will insist that your book conforms to their “hashkafa”.
Someone mentioned to me how some secular author was forced to put a gay character in their book, or else the publishers wouldn’t publish it. I don’t know who this was, or whether she was famous, but if anyone could name her, I’m sure the info could come in handy.
