The Gray Man- Agente Oculto

The book's realistic portrayal of spy operations really immerses me. I'm curious whether the author drew from personal experience or extensive research.

The way the story reveals bits of the Gray Man's history kept me hooked, but I wonder if the pacing affected the suspense for others too.

The story kept me on the edge of my seat — I wonder if the rapid pace was planned to mirror the protagonist's urgency or evolved naturally.
