Careful, this is not a sequel, nor a prequel, nor a novel. It's non-fiction and despite the age of the book still read-worthy! Huxley compares his novel with the society he lives in about 30 years after BNW was published. And we still deal with all the topics he mentions: overpopulations. surveillance, ressources. While I reading I often had images of recent events in mind and I wondered what Huxley would say to the world at its current stage.
