This is a classic look into a dystopian future, but a future that has disturbing parallels with the way we live today.
A mix of genetic engineering, brainwashing and recreational drugs and sex has turned everyone into happy consumers, who are unable to question or to feel real emotion. From babyhood people are conditioned to avoid becoming connected with other people or with nature and conditioned to accept life as it will be for them in their predetermined social category. People die in dying homes where the TV volume is turned right up and no-one visits except school groups on tours to get them conditioned to accepting death as something that doesn't matter.
So in the ultimate sense everyone is alone, but at the same time in everyday life they're pressured into constant communal activities and aren't allowed time by themselves, until they get old and socially unacceptable.
Bernard Marx, the main character, somehow has maintained enough individuality to question what is going on and travels to one of the few remaining Savage Reservations where he finds life being lived as it used to be, full of the possibility of the whole range of human emotions.
This novel (written in 1932) is still a glimpse into a future of genetic engineering and social control, while offering insights into the way we live today.
