When the Lights Go Out by Carys Bray

If you believe your world is going to end, how should you live? And what if, while preparing for disaster, you unwittingly precipitate it? While Emma Abram prepares for Christmas, her husband Chris frets about starvation and societal collapse. Desperate times call for desperate measures. Chris has turned off the heating. He treks his sons across the Moss in the drubbing rain. And he has other plans that, if voiced, Emma would surely veto. But it's easier to ask for forgiveness than permission. Emma longs to lower a rope and winch Chris from the pit of his worries. But he doesn't want to be rescued or even reassured - he wants to pull her in after him.
