The theme of mystery might also be present. The identity and nature of the 'night prince' himself could be a mystery. His origin, his powers, and his purpose could all be things that the story gradually reveals to the readers, keeping them intrigued throughout the novel.
Romance is likely to be a main theme. Since it's a 'night prince', there may be some sort of love story involved, perhaps between a human and the prince.
Another theme could be the supernatural. A 'night prince' implies something otherworldly, so there might be elements like magic, special powers, or a different realm in the story. It may also deal with themes of good and evil, as often stories with supernatural elements do, where the prince may be fighting against some form of darkness or vice versa.
