Sous un ciel écarlate

The protagonist faces impossible choices that made me wonder how I would react in such situations. Did the author intentionally blur the lines between right and wrong?

Knowing it's based on true events added a layer of depth, but I'm curious what sparked the author's interest in this particular story of heroism and survival.

The vivid descriptions made the setting come alive, but I wonder if the author traveled there or did extensive research to capture the atmosphere so authentically.
