El infiltrado (Umbriel thriller)

The sequence felt incredibly realistic and tense. I'm curious if the author drew from real events or crafted it from imagination to heighten the stakes.

The way characters grappled with tough choices made the action scenes even more impactful. How did others connect with their internal conflicts?

The technical aspects added authenticity without slowing down the plot. I'm interested in whether this balance was planned or evolved during writing.
