Der vergessene Feind

The pacing kept me guessing, but I'm curious about the specific techniques used to build tension. Did the author plan the suspense points in advance or develop them during writing?

The characters' grief and trust issues felt so real that I found myself thinking about them long after finishing. How did the author develop such authentic emotional depth?

The setting felt so vivid and atmospheric — I wonder what led to selecting this location and how it influences the story's mood.
