Doomsday rewind:no more mercy

Serena never expected the world to end in fire and screams. She also never expected to die betrayed, starving, and alone.

When the virus outbreak turned cities into feeding grounds for the undead, Serena fought to survive. But the people she trusted most—her best friend and the man she loved—stabbed her in the back. They stole her supplies, locked her out in the chaos, and watched as she was ripped apart.

But fate had other plans.

Serena wakes up three months before the apocalypse begins. This time, she’s not weak, not naive, and definitely not forgiving. Armed with her knowledge of the future, she will stockpile supplies, fortify her safe house, and make sure no one takes advantage of her again.

And those traitors?

They have no idea the girl they betrayed is coming for them.

The world is ending, but Serena is just getting started.
