When I re-read this recently I was surprised by the old fashioned nature of the writing and the extent of John Wyndham's vocabulary. It is a science fiction book written in a style we don't see today. However I wasn't surprised to find the story was still gripping and thought provoking. It is an excellent book on so many levels.
I might add that this Penguin Classic edition is nicely printed and easy to read, but they haven't covered themselves in glory by their choice of cover image. Yuk. Really!
