Then something big and devastating happens, and we move into a new phase of the book, showing the consequences of a story we only half-know and taking us to some weirder places. Eventually the book returns to telling the original story, but in a more fractured way, and it’s a little bit frustrating – as if someone cracked the television screen halfway through watching a film. Another consequence is that from this point on the reader has reason to doubt what we are being told is happening, which inevitably places a barrier between the story and our emotions. But it’s still a good story, even told this way.
The ending was disappointing at first, then a bit less disappointing after thinking about what it meant for earlier parts of the book, and then disappointing again when I started to ask myself what the plan was ever meant to be. But as a warning of environmental catastrophe, the book is very effective, and its portrayal of social breakdown is convincing. And I loved its depiction of the high-pressure situation on board the Polar Horizon, the effect that loneliness, lack of sleep, secrets, money and sex would have on people spending far too long together in close quarters.
