Maybe the unique setting of night could make it interesting. The things that happen at night often have a different feel.
The 'night soldiers novel' could potentially revolve around a group of soldiers who are assigned special missions that take place at night. It might explore themes such as courage in the face of darkness, the bond between comrades during dangerous night - time operations, and the challenges that come with fighting or carrying out tasks when visibility is low. Maybe it also delves into the psychological aspects of soldiers in these situations, like how they deal with fear and uncertainty in the dark.
The historical accuracy makes them unique. Furst does a great job of researching the time period.
Mystery makes a night story interesting. When there are elements that are unknown and make the reader or listener wonder what will happen next. For example, in a night story, if a character hears strange noises in an old attic at night, that mystery draws people in.
The characters are interesting because of the racial tensions they represent. For example, Virgil Tibbs being a black man in a predominantly white and racially charged small town in the South. His interactions with the white characters, especially Bill Gillespie, create a lot of drama and conflict.
The excitement and unexpectedness. A crazy night novel can be interesting because it's full of surprises and wild events that keep you on the edge of your seat.
The unique atmosphere and mysterious elements of a night carnival can really draw readers in. The colorful lights, strange characters, and unexpected events all add to the appeal.
A hot night story becomes interesting when there are strong emotions involved. For instance, if you're at a hot night party and you have a moment of deep connection with someone you just met. The heat of the night, combined with the new relationship, creates a story full of excitement and anticipation. Or if there's a bit of danger, like seeing a snake slither by on a hot night hike, that also makes for an interesting story.
One popular 'night soldiers novel' could be 'The Nightingale' which has elements of soldiers during war time and the story often unfolds at night. It's a great read with strong characters.
Since I haven't read it, I can't say for sure. But it might be the soldiers themselves, perhaps a brave captain leading the night operations or a young recruit learning the ropes of being a night soldier.
The mystery aspect. When a book is set at night or has a lot of night - time related elements, it naturally creates an air of mystery. For example, in a night visions fiction book, things that are hidden during the day might be revealed at night.
