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.

When the apocalypse struck, Ray Morley was brutally murdered and eaten by his wife's family. Only in his dying moments did he learn the cruel truth—his beloved son wasn't his own flesh and blood. He had been nothing more than a pathetic stand-in, a fool used and discarded. But fate gave him another chance. Reborn three months before the end of the world, Ray awakened to find himself in possession of an enormous, otherworldly storage space. This time, he wasted no time—he divorced his venomous wife, won a massive lottery prize, stormed into the stock market, and earned billions. He built fortified shelters and hoarded mountains of supplies. In this new life, he would make his ex-wife and her family pay—every last one of them. No more groveling. No more weakness. This time, Ray would rise above it all.

Natasha Reese believed love could survive the end of the world. She gave up everything for Josh — her dangerous past as a special forces operative, her freedom, and her deepest secrets — to build a safe home with the man she loved. But when his childhood friend Evelyn stepped into their lives, Natasha watched her marriage slowly crumble. Her husband grew distant. Her mother-in-law turned against her. And when her hidden truth was exposed, the man she adored cast her out into the dead world to die. She should have died. Instead, Natasha rose stronger than ever, leading an elite strike team and carrying a power that could save what remains of humanity. The infected won’t touch her. The survivors look to her with hope. But when Josh returns, haunted by regret and desperate to win back the heart he broke, he finds Natasha in the arms of another man. Aaron Ross — powerful, dangerous, and willing to burn the world down for her. The only man who offers Natasha the kind of love and devotion Josh never could. Now torn between the husband who betrayed her and the man who wants to claim her completely, Natasha must make a choice that will decide not only her heart… but the future of humanity itself.

In a world fractured by the "Gray Death," the end didn't come with a whimper, but with the rise of the Beastkin predatory survivors with the strength of monsters and the hearts of kings. Rhea, a trauma intern turned scavenger, has learned the hard way that mercy is a luxury the ruins cannot afford. When she is betrayed by those she loved most and left for dead in a crumbling bakery, her only companion is a soot-covered stranger she pulled from the rubble of Sector 4. She thinks she’s saving a nameless survivor. She has no idea she is nursing the Ghost King back to health. Dominic is the Alpha of the Northern Citadel, an untouchable god of war hunted by his own kind. Broken and hiding behind a mask of amnesia, he watches the woman who saved him with a growing, predatory hunger. She is the "Diamond in the Ash," the same girl who held his hand in a dark pharmacy three years ago when the world first burned. As the heat between them ignites into a passion that threatens to consume the ruins, the shadows are closing in. While Rhea drowns her sorrows in vintage wine and dreams of a touch she thinks she’ll never have, Dominic’s "Men in Black" are quietly securing her borders. He came to find a traitor, but he found a Queen. Now, the Alpha will stop at nothing to reclaim his throne and build a new kingdom, one where the woman who showed him mercy finally gets the crown she deserves. He’s a King in hiding. She’s a healer with a broken heart. Together, they are the apocalypse’s last hope.

The end of the world was upon us, but there weren't enough spots for evacuation. The roars of the zombies echoed in my ears as my fiancé, Oliver, gritted his teeth and pulled me onto the rescue vehicle—securing the last available seat. I arrived safely at the survivor base. Lina, his first love, did not. The zombies tore her apart. Oliver still went through with our marriage, but I never expected that he had only done so to make me suffer. In his eyes, I was the one who had killed Lina. If she had to endure such agony, then I should, too. For five years, he hated me. My life was worse than that of a stray dog scavenging for food on the street. On the day my divorce was finalized, he kidnapped me, dragged me into the wilderness, and wrapped his fingers around my throat. Then, he threw us both into the swarm of the undead. When I opened my eyes again, I was somehow reborn on the day the apocalypse began. The rescue team was shouting impatiently, "One more! We have room for one more—hurry!" I turned to Oliver, watching his hesitation. Then, with a quiet smile, I took a step back and let someone else have the last seat.

Humanity has finally done it and destroyed the world. After the spread of the killer virus that no one had a cure for, countries started to fight as greed has pushed them to expand their territories. And in the process, they provoked mother nature to take a stand. The plague evolved into something that twisted and deformed humans; they were neither dead nor alive. Just walking empty husks that fed on flesh and had one purpose, killing. The supernatural were exposed to the rest of the world; as they weren't spared and got affected, too. The result of this knowledge was chaos. Instead of creating one unity, the rest of the living were fighting among themselves and the undead. The entire world turned into a big arena and it was (survival of the fittest).
