So now I have to try and write a review without giving *anything* away about this book. Like 'The Martian' (that I read nearly a decade ago!) it feels like a book that will make an excellent film ... the end of the world is nigh, how would you behave, what would you need to survive, will technology save the day ...
It is a portrait of the power of wealth, and of inequality, and of how the super rich do seem to live on a different planet from the rest of us.
That's all I can say, anything else would step into spoilers.
Stay safe. Be kind. Be prepared.
