Set at an isolated Arctic research station, the Zodiac Station books put characters under pressure by stripping away the usual comforts and escape routes. Tom Harper uses the extreme environment as more than backdrop, letting the cold, the darkness, and the distance from the outside world shape how characters behave and how secrets stay buried. Polar Vortex introduces the setting with a mystery that builds slowly before accelerating.
The second book, Zodiac Station, expands on the same themes of institutional cover-ups and survival in hostile conditions. Both books suit readers who enjoy thrillers where geography does real narrative work, and where the pace allows tension to accumulate rather than relying entirely on action. They work well as a pair, read in order.
