Cave Resident Evil <2> nightmare (C ?NOVELS)

The isolation amplifies the horror and suspense, but I'm curious whether the author drew from real places or created it purely from imagination.

The story raises questions about what people are willing to do when faced with life-or-death situations. Did this make others uncomfortable or did it deepen the story for you?

It felt like a fine line, and I wonder if the blend was planned from the start or evolved during the writing process.
