Malcolm King is a journalist living in trendy Hove on the south coast of England. His days are taken up with video meetings and research on the internet while he writes articles for magazines around the world. When a solar flare of unprecedented magnitude hits the Earth, effectively hurling us back to the stone age in a matter of hours, Malc is thrust into a terrifying new world as he travels the length of the country to find his young daughter. Society, a fragile construct at best, shatters as the survivors fight each other for food and water, neighbour killing neighbour as fires rage through the cities, destroying much of what’s left. Faced with difficult choices at every turn, Malc draws his strength from those around him; Emily, a tough, no-nonsense soldier with a soft spot for lost causes and Jerry, a disgraced astrophysicist who may be the only person left who understands what’s happening with the sun. With their help, he must struggle to answer the ultimate question. What won’t he do to get his daughter back?
