They still have each other, which is at least the only real and existing thing in the apocalypse.
No cp = eat as you like, multiple viewing angles. There are a lot of uncomfortable descriptions, probably.
Modern apocalyptic novel, the zombie virus breaks out, and everything is over.
Very dark humor, and the description is sensual.
Not much about knives because it's funny for me to write about knives.
Concept: A story that is not very knife-like, but full of black humor.
