Hasta el fin de tus días

The pacing kept me on edge, but I wondered whether the tension was planned from the start or evolved during writing. What techniques did the author use to keep readers hooked?

The characters' psychological struggles felt raw and authentic, but it also made me uncomfortable at times. How do others interpret the book's handling of trauma?

The sense of place added a lot to the mood—was this influenced by real locations or purely imagined? I'm curious about the author's creative process here.
