I'm not sure exactly as I haven't read it. It could be about various things. Maybe it's a story that unfolds in the daytime and has themes related to clarity, discovery, or new beginnings that are often associated with daylight.
Well, without having read the novel, it's difficult to give a detailed account. But generally, a title like 'the clear light of day a novel' might suggest that the story is set in a context where truth and understanding are central. It could be about a journey of a character or characters towards enlightenment or the resolution of some sort of mystery that is brought to light, perhaps like a mystery that is finally solved when all is visible in the clear light of day.
Since I haven't read 'the clear light of day a novel', it's hard to say precisely. However, it might deal with characters' lives being exposed or made clear, much like how things are visible in the clear light of day. It could be a story of self - realization or the revelation of secrets.
