It could be a coming - of - age story. Since it's about a girl from a particular place, it might focus on her growth and development.
I haven't read this novel specifically. But generally, a novel with a title like this might be about a girl from a place called Summer Hill. It could explore her life, her dreams, and the unique aspects of the Summer Hill community.
Maybe it's a mystery. If there are elements of the story that are unknown or need to be uncovered, it could fit into the mystery genre. For example, if there was a strange event that happened on the hill and the characters are trying to figure out what really occurred. Also, if the hill has some secrets that are gradually revealed throughout the story, it would add to the mystery. Another possibility is that it could be a documentary - style genre if it's a very factual retelling of the events that happened on the hill, with real - life footage or interviews perhaps.
Love is a very common theme. The relationships between the characters, whether it's romantic or platonic, are often explored in depth during this summer setting. For example, new romances might start or old ones might be rekindled.
It might be a coming - of - age story. A single summer can be a time of great change and self - discovery for a character, especially if they are young. So it could be about a character growing up and learning important life lessons during that summer.
It could be a mystery genre. Since it involves 'the night child', there might be a lot of unknown elements and secrets to uncover.
It could be a mystery genre. Given the mention of'secret guests', there are likely elements of secrecy and discovery, which are typical in mystery novels.
It could be a family drama. Given the focus on the mother's sins, it's likely to involve a lot of family interactions and conflicts which are typical of the family drama genre.
It could be a literary fiction. Since it focuses on the concept of colors in a novel form, it might be more about exploring complex themes and characters rather than fitting into a more commercial genre like action or romance.
It could be a thriller. If things come in threes in the story, it might be related to a series of three dangerous events or threats that keep the reader on edge.
It might even be a romance novel. The moons could be a romantic backdrop, like a place where the characters meet under the light of the moons, and the 'thousand moons' could symbolize the long - lasting or numerous encounters of the lovers.
