When a massive near-Earth asteroid is detected on a collision course, the world unites in a desperate race against time. Probes are launched, nuclear warheads armed, and plans devised to deflect the rock. Every attempt fails. The asteroid strikes with catastrophic force, shattering cities, boiling oceans, and blotting out the sun. In a single day, ninety percent of humanity is gone, and the survivors awaken to a planet forever changed.
In the wake of the asteroid’s devastation, the world has returned to a wild state. Forests reclaim roads, and predators roam freely where cities once stood. Among the scattered survivors, Rhea hunts to stay alive, recording each day in her diary. Thirty-eight days have passed without seeing another human. Determined to find signs of life, she decides to head south, wary of what waits in the untamed land.
