Vivo o muerto (Umbriel thriller)

The story feels so real and timely—I'm curious if real-world events or research influenced the depiction of spy operations and diplomacy.

The pacing was relentless, but I wondered if the sudden escalation was a deliberate choice to keep readers on edge or if it could have been more evenly built.

The interactions between the agents and villains felt layered—what do readers think about the way personal and professional conflicts were woven in?
