Writing a plot for a thriller novel that takes place in an abandoned city can be tricky. It all depends on what the protagonist will do to survive in this place.
To start off, you need to know what your protagonist does for a living and how they feel about the abandonment of the city. They could be an architect who has lost their job or a journalist working on a story about this abandoned location.
The story might start with them arriving at the abandoned city and getting more and more curious about it. They might explore it, find something strange happening there, or meet someone who lives there illegally.
