- Description from Novelupdates

I never imagined this would happen to me. Reincarnation? A second chance? Into a fictional world, no less? It was the stuff of wild stories, impossible dreams, and late-night “what ifs.” But life has a funny way of playing with your expectations.When the choice was offered—life as I knew it or a chance to die and be reborn somewhere else—how could I say no? The catch? I wouldn’t return to just any world. No peaceful afterlife, no utopia waiting for me. Instead, I landed in the heart of chaos.Here I am, standing in the shadows of giants—of gods, heroes, and monsters. Welcome to the Marvel universe, where cities are playgrounds for battles that could shake the world, and everyday people like me are nothing but collateral damage.But I’m not just another face in the crowd anymore. Somehow, I’ve got a role to play. My name in this world is Dave Garcia, and this is the story of how an ordinary guy from another life navigates a place where the impossible is an everyday reality.What would you do if you woke up in a world where the fate of everything could be changed with a snap of the fingers? Because that’s exactly what I’m trying to figure out.
