The Endless Night
In a parallel universe, Margo Kinnear was Prime Minister of the United Kingdom.
When the Sun was extinguished, Margo made a radio announcement, informing listeners that the Sun had indeed burned away to nothing, leaving no prospect of survival for the Earth. She ended her broadcast with a note that it had been her honour to have served as Prime Minister, and would spend her remaining time with her family. (The Endless Night)
