A good end-of-the-world story. It's very dated, both in the scenario and language, but remember, this is from before the worries about global warming and before calling black men Sambo and assuming they were inferior was thought to be perhaps not in the best of tastes. I refuse to judge a book badly simply because of when it was written. But unfortunately, it is let down by an unconvincing ending, in which the main character's motivations and the new life he has created for himself get turned on their head for completely incomprehensible reasons. Still worth reading though if you can find it for a few pennies second-hand.
