I love John Wyndham so this was good to read. As a story I found it to be a slow builder. There is a lot of technical detail and references to various organisations. The story plays out with great believability.

Taken as a science fiction thriller, it lacks obvious confrontation and the usual head on battles you get from Hollywood. This makes it different and doesn't bother me. It feels like a child of its time.

The rising of the water must stand as a stark warning to us in the climate change century. Wyndham has no romance or human heroics in this scenario. Selfishness and combat is what the human race falls back on when under pressure. I hope he is wrong because the high tide is coming.

Worth reading!
