El último pasajero (Tapa dura con sobrecubierta)

The confined setting adds so much tension and claustrophobia. I'm curious whether this was inspired by real train journeys or purely fictional.

It felt like the tension dipped before ramping up again. Was that intentional to build suspense or a natural part of the story's flow?

The supernatural aspects felt fresh and unsettling. I wonder what the author’s influences were in shaping this mysterious force.
