I don't know the main characters in 'the river at night novel' since I haven't read it. It could be a lone wanderer who is drawn to the river at night, or perhaps a group of friends who have a special connection to that place.
Without having read the 'the river at night novel', it's impossible to say for sure. But it might have a young protagonist, maybe a teenager who is exploring the area around the river at night and discovers things that change their perspective. There could also be an older figure, like a wise hermit who lives near the river and imparts some kind of knowledge to the other characters.
As I'm not familiar with this novel, I can only guess. There could be a fisherman who has spent his whole life by the river and has many stories to tell. Maybe there's a young couple in love, and the river at night is their special place. There might also be a villainous character who uses the cover of the night by the river for some not - so - nice purposes, which would create conflict in the story.
