The year is 2133. The story takes place in a town and the narrator/main character is Caleb Ramirez. He is currently surviving an undead outbreak.
He needs to scavenge for food all the while finding survivors and killing the infected.
He finds a good place to gather fresh food and while he is there he fights off a zombie in an over-detailed battle and rescues two survivors.
The survivors and Caleb become friends and they go on a quest to find other survivors whilst removing zombies one by one from the planet. A little bit later, one survivor dies from illness.
As the survivor and Caleb go around they find and gather more and more survivors, they create a huge group and have to find and create weapons to relieve themselves of the stress and pain the undead produced.
They manage to create a well-run community and slowly start to rebuild society while traveling around the country.
