I suppose the alternative title could be called 'Shades of Grey'. No, there's nothing of an explicit nature here. Instead it is the story of a young woman who only judges things in absolutes, as polar opposites, with no concession as to what might fall between the spectrum -- and all by the yardstick of her own morals and scruples. She meets a fella who is completely opposite, and yet complements her. He sees (or tries to) the heart of things, and understands and accepts their varied kaleidoscopic outcomes. A light and fun read.
