It might be a science - fiction or fantasy genre. There could be some sort of advanced technology or magic that enables the character to refuse the second execution. For example, if it's science - fiction, perhaps the character has been cloned and the first execution was of the clone, and now the real person is fighting to avoid the same fate. In a fantasy setting, it could be a magical spell that saved them from the first execution and they are using their new - found knowledge to avoid the second.
I think it might also be a psychological thriller. The idea of disappearing can be very psychological in nature. Maybe the story is about a person's mental state leading up to their disappearance or the psychological impact on those around them. It could explore deep emotions, fears, and traumas, which are common in psychological thrillers.
It could be a coming - of - age genre. Many stories about a first time experience are related to growing up and learning new things, which are typical elements of coming - of - age stories.
I'm not familiar with this 'i refuse to be executed a second time novel'. But from the title, it might involve themes of justice and injustice. It could be that the main character has some special power or knowledge that makes them able to resist the second execution. It could also be a story about redemption, where the character has changed since the first execution attempt and is now determined to avoid a second one for a good cause.
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.
It could be a romance genre. Maybe the coast road is the place where two lovers meet and their relationship develops against the backdrop of the beautiful coastal scenery.
