Trivia / Down to a Sunless Sea

• Spared by the Cut: In the first edition of the book, all but two of the four hundred or so survivors succumb to radiation sickness, with the last pages setting up an Adam and Eve Plot. However, the author quickly grew dissatisfied with this ending and re-released the book, revising the ending so that the fallout stops short of the Antarctic Circle. On top of, Antarctica becoming warmer due to the nuclear war altering Earth's axial tilt means that the characters aren't at risk of dying of starvation or cold, so they're able to rebuild civilization on the South Pole.
