In a world reliant on technology, the bright flashes in the sky were just the beginning. With the power gone, the UK falls into a state of panic. The ensuing anarchy is simply a warm-up act. Shaun Taylor is stranded far from home, far from a broken family he needs to make whole again, and he will do whatever it takes to get back to them. What would you do to get home? What would you do if the lights went out?

In the aftermath of the destruction, Shaun finds himself trapped by the winter. With little other choice, he joins a group of survivors doing the best they can. His idea of best isn’t always shared by the group, but before the weather breaks, when he wants to resume his journey, they all face conflict. Miles away, doing the best that she can, Abbie is adapting to life without power; only, her own situation is far from ideal. After the sound of the falling bombs fade, as the dark world they live in tries to recover, they have to find a way to adapt to their new reality.

The bombs weren’t the end. They weren’t even the beginning. As winter ebbs away, the true horror emerges. Shaun, reunited with Abbie, struggles with he emotional rollercoaster of searching for Lydia. Each day they don’t find her is another day she could be further away.
