Aux portes de l’éternité

The depiction of historical events felt very detailed and nuanced. I'm curious whether this was based on extensive research or a personal passion for the era.

The story's portrayal of family bonds amid chaos was powerful, but also heartbreaking. Did any particular character's journey resonate more deeply?

Following multiple generations gave the story a grand scale, but I wonder if this was planned from the start or developed during writing.
