Les Temps parallèles

The narrative jumps between eras in a way that keeps me guessing about the characters' connections. I'm curious whether this was planned from the start or developed as the story evolved.

The dilemmas they face are so layered, making me wonder how much the author intended us to sympathize with their actions versus question them.

The detailed world-building really pulled me in, and I wonder what sources or ideas inspired the author to create this particular universe.
