An apocalypse driven by natural disasters. Survival of the fittest. Typhoons, floods, deadly cold, scorching heat, earthquakes, tsunamis, insect plagues, acid rain… After struggling through three years of the apocalypse, Nicole Floyd met a brutal death. Miraculously, she woke up and found herself three days before it all began. Nicole seized the advantage to reclaim her storage space, flipping the switch on full-on stockpiling mode. She shopped until she ran out of money, and her storage was packed tight. She also looked for the dog that had saved her life once before. She sharpened her knives, stacked her supplies, and took care of unfinished business. She paid back every debt, whether owed in blood or in kindness. And then, disaster struck. Her right hand gripping a knife and her left stroking the dog, Nicole pressed on through the ruins of a world without order or morals.
