I'm not sure specifically as there could be many novels with this title. It might be about a house made of sand, perhaps metaphorically representing something fragile or impermanent in the story.
Well, without having read the 'House of Sand Novel' directly, it could potentially be about a family living in a house near the sand, like on a beach. And the story might revolve around their experiences, such as dealing with the elements, or the isolation that comes with living in such a location. It could also explore themes like the passage of time and how the house and the people in it change over the years.
