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.

After cutting ties with her ungrateful ex and his parasitic family, a mysterious voice awakens in her mind, LUS, a Level-Up System designed to help her survive the coming end. With knowledge of the future and a system guiding her every move, she begins to prepare. She stockpiles resources, builds a base, and learns how to fight back against the horrors that once destroyed her. And when the apocalypse arrives again… she’s ready. But survival isn’t the only thing waiting for her in this new life. A silent killer who watches her like prey. A manipulative genius who wants to unravel her secrets. A gentle protector who sees the girl she hides. And a dangerous man who thrives in chaos.

Because now, the man who once abandoned her is back, broken, desperate, and begging for a second chance. Too bad she has no time for regrets. Not when she’s busy rising to power… and building a kingdom in the ruins of the world.

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).
