Zombie Rules

The book's title suggests a set of unspoken laws for navigating the apocalypse. I'm curious whether these rules were inspired by real survival tactics or purely fictional ideas.

Some decisions seemed to blur the line between right and wrong, which made me question what I would do in their place. How did the author approach writing morally gray characters?

The world-building felt very tangible and immersive. Wondering if the author drew from personal experiences or other dystopian stories to craft this environment.
