Not being a native speaker, and reading it when I was quite young, I first had some problems with the John Wyndham's sometimes intricate sentence structure. Soon, however, I came to enjoy the different ways he uses the syntax.
Too, it is a book with the typically British brand of subdued sense of humour. You MUST read Diana's idea of getting her discovery across... hilarious!
Wyndham employs vivid characterisation of the two protagonists, and he always does it with sympathy. Rather unusual for a sci-fi writer of his time and age is that he remains mainly with the woman's point of view. In other novels they are little more than big-busted damsels with zero watts of brainpower to be rescued from slimy aliens (I wonder what made THEM long for a human mate of such little promise for the gene pool!).
There is plenty of food for thought.
Would you want a longer life at all costs, meaning killing people for it?
Should you want it, if it means more of the same boring life?
Who would be eligible?
Are male/female stereotypes still valid in the modern world?
All in all, it is an evergreen and should be in every serious sci-fi collection.
