A lot of people seem to love it, so maybe I´m once more the odd one out. But I have the slight suspicion that this book is his weakest work. I will definitely read another one of his books, just because I really liked The Day of the Triffids and I´m not giving up on Wyndham just yet.
I did like The Day of the Triffids, too. This one doesn't sound interesting though. You should try "The Chrysalids". It's a post-apocalyptic scenario with a hopeful ending and a strong message imho.
