A time-travel thriller about the end of the world … and one utterly broken man’s fight to stop it.

As the known world is completely destroyed, Sergio Alvarado is among the few who witness the end. But in a twist of fate as strange as it is impossible, he wakes up 3,333 days in the past — on October 7, 2003. With the memory of the apocalypse etched indelibly in his mind, Sergio is given a once-in-a-lifetime chance: to prevent the catastrophe before it happens. Driven by the desire to save his family and tormented by a future no one but he believes in, Sergio finds himself trapped between two timelines: one that has already happened, and one he is desperately trying to change. But the more he rebels against fate, the more obstacles rise in his path: disbelief, bureaucracy, his own inner demons … and the relentless weight of time itself.

3333 Days is an exciting and emotional science fiction novel that blends time travel, psychological suspense, and apocalyptic thrills into a profound story about survival, regret, and the price of knowledge.

The end is near. The question is: Will anyone believe him in time?
