I am in the process of writing a science fiction novel and am considering casting an entire city as a POV character. I do believe that I've read a novel with something like this before, but I cannot recall a specific book. I know there are a lot of examples of sentient setting, but it's usually manifested in individuals -like character constructs in the Matrix, or like living trees, etc. in fantasy books.
Can anyone recall reading a sci-fi novel with a sentient setting as narrator or POV character?
