Think about the end of the world. Everyone knows the zombie trope, but Mortals of the Doom flips the script by cranking the pressure to the absolute max. Our protagonist lived through the hell of a virus-carrying meteorite once before and did not make it. Now, he has somehow been thrown back in time to his old high school classroom. But here is the catch: he does not have years or even days to prepare for the end. He has exactly ninety minutes before the sky falls and the walking dead take over.

This is not just another survival story. It is a desperate race against a ticking clock where every second counts. Between the supernatural mystery of his rebirth and the sci-fi horror of the impending plague, he has to navigate high school drama while gearing up for total global collapse. With his future knowledge, he might be the only one who can survive the initial wave of slaughter, but saving his own skin is only the beginning. Expect heart-pounding action, unexpected romance amidst the ruins, and a brutal look at what happens when the world ends before your first period class is even over.
