Infiltrado: Uma série de suspenses do espião Agente Zero — Livro nº1

The character's past feels layered and intriguing—I'm curious whether the author developed it early or discovered it during writing.

The story moved so quickly that I struggled to keep up at times. Was that the goal to reflect the urgency of espionage, or did it affect immersion?

The contrast kept the story dynamic, but I wonder if the pacing was carefully planned or evolved naturally through writing.
