The Cost. The Battlefield Z Series

THE COSTA Post-Apocalyptic Survival ThrillerIn the end of the world, mercy is never free. Kai survives by one rule: never spend more than you can afford to lose. In a scorched countryside haunted by predators-both human and undead-every decision is a calculation, every act of kindness a potential death sentence. When Kai discovers a wounded man trapped beneath a collapsed farmhouse, she makes a choice that could cost her everything.
Saving him means risking her supplies, her safety, and her hard-earned isolation. Leaving him means becoming something she swore she wouldn't be. She chooses to help him. That choice becomes a trap. Robbed, betrayed, and left barefoot to die, Kai is forced into a brutal reckoning. Stripped of weapons, food, and trust, she turns pain into currency and the land itself into a weapon. What follows is a relentless battle of wits between hunter and prey-one where survival depends not on strength, but on who understands the true cost of cruelty.
Perfect for fans of post-apocalyptic fiction, zombie survival novels, grim dystopian thrillers, and character-driven end-of-the-world stories in the vein of The Road, Station Eleven, and The Walking Dead. In a world without laws.Every choice has a price. And someone always pays.
