Looking for a sci-fi or fantasy taking place on a Tidally Locked Planet.
A tidally locked planet is a planet that doesn't rotate on it's axis like Earth does so one side is permanently facing the sun while the other side is in perpetual darkness and due to this the world experiences extreme temperatures with the sun side being a boiling inferno and the dark side a frozen wasteland. The border where these two hemispheres meat is called the Terminator or Twilight zone and hypothetically the only place with tempered, habitable, climate on such a planet.
I'd love to read a fantasy or sci-fi with a civilization that lives on this narrow strip of land circling the world sandwiched between a burning hell on one side and a freezing hell on the other side.
