"I think my boyfriend is trying to kill me." For three months, Valerie thought she was the luckiest girl alive, living in a luxury penthouse with a man who seemed entirely too perfect. But when a record-shattering heatwave strikes the city, plunging the world into a stagnant, fifty-six-degree incubator, the perfect mask slips. Julian doesn't sweat. He doesn't breathe. And he isn't human. Trapped in a dead apartment with a cold-blooded apex harvester who views her as nothing but prime genetic livestock, Val is forced to rely on her sharpest instincts just to survive the night. But as the old world rots under the scorching sun, her desperate defiance triggers an evolutionary spark within her own neural pathway: a mysterious, conceptual ability known as [Cardify]. The apocalypse has arrived, but Val is no longer playing the victim. In a world turned into a deadly wonderland, she will flatten her enemies, pocket the ruins of civilization, and rewrite the rules of survival—one card at a time.
