Defiance of the Fall 5

The pacing and world-building keep me on the edge of my seat. I'm curious what techniques the author used to maintain this intensity across multiple books.

Some decisions seemed morally grey, which made me question what I would do in their position. Am I the only one who felt uneasy about certain actions?

It feels both innovative and integral to the story's survival themes. I wonder if the author drew from existing mythology or created it from scratch.
