Vera fought for her life in the apocalypse for ten years. Ten brutal years left her disfigured, hungry, and almost broken, but she still clawed her way through it. She killed zombies, ran from mutated animals, starved, bled, and learned humans were often more dangerous than monsters. Then her brother, the only family she had left, betrayed her. Vera thought death had finally come. Instead, she woke up inside a trashy book she once read to stay sane while the old world fell apart. A book with a twisted plot and too much drama. And because her luck had always been terrible, Vera did not wake up as the heroine. No, of course not. Her second chance was to become the hated second female lead, pregnant, unwanted, and written to die when the plot no longer needed her. Her babies were supposed to die too. Even the three men who got her pregnant were written as future corpses, all to push the story toward spoiled women and one psychotic male lead. But Vera was not the woman from the book.

Now the woman meant to disappear is building a wasteland empire, breaking the plot, and driving three men insane because she no longer chases anyone. By every rule in that world, Vera should be dead. But dying a second time was never an option.
