Black Virus

The world-building feels so visceral and authentic, but I wonder if it was inspired by real events or pure imagination. How did the author craft this harsh environment?

The characters are pushed to their limits, and their decisions often blur the line between right and wrong. Did this make anyone else question what they'd do in similar circumstances?

The story moves so quickly, almost breathless at times. I wonder if the fast pace was planned from the start to heighten tension or evolved naturally during writing.
