I'm not sure. But it's possible. The Stranger Things world is full of strange creatures from the Upside Down, so the new novel could introduce some new ones.
Stranger Things wasn't a novel to begin with. It was developed as a TV production, and its unique story and characters were brought to life through the medium of television.
Stranger Things isn't based on a novel. The idea originated within the creative minds of the show's developers and was crafted independently for television. It has its own unique story and world-building.
There could be a new character who is a psychic like Eleven but from a different part of the world. This character could bring in new knowledge about the Upside Down and different ways to combat it.
Well, characters like Max moved to Hawkins. Her back story involved dealing with a difficult family situation at home, with an overbearing step - brother. But in Hawkins, she became part of the group facing the strange happenings. And then there's Will. His back story includes being abducted into the Upside Down, which led to a whole series of events that involved his friends trying to rescue him and uncover the secrets of the alternate dimension.
A whole new story in Stranger Things could come in the form of new characters, unexpected plot twists, or exploration of previously uncharted aspects of the show's fictional world. This keeps viewers engaged and on the edge of their seats.
