Les Jeux de Némésis

The narrative shifts between several characters' perspectives, and I wonder what guided the author's choice to tell the story this way. Did it help build suspense or deepen the world-building?

The pace seemed to pick up dramatically after the halfway point, which kept me on the edge of my seat. Was this intentional to mirror the chaos in the story?

The detailed world-building created a vivid backdrop for the story. I'm curious whether the author envisioned this universe from the start or developed it as they wrote.
