This was very, very up my alley, and I'm so glad I ordered a copy immediately after watching Dead Good Book Reviews' review. Her comparison to the Doctor Who episode "Midnight" is apt, and I will never not be interested in an unsettling story set on a train. Fear of the unknown, human nature, and anticapitalism come together in a most excellent and weird bundle that verges on horror (with fungus and a bit of body horror, my faves). The 0.25 deduction is because I would've liked to see more character development. I think the level of depth we get works for the story, but it would've been even better with more imo. Very excited to see what Brooks writes next!
