Doomsday rat

Doomsday, zombies, individuals, groups...
I have also read some doomsday-themed novels, but I always find them unreasonable and logical.
Some people say that science fiction should not be logical, and it will not look good if it is too realistic.Indeed, including many Hollywood blockbusters is not the same logic.
But I just can't get used to it. I always feel that under the premise of being in line with common sense and close to logic, it should be able to build a wonderful plot.
Is it possible?This book is the answer, just wait and see.
