Empty World by John Christopher (1977) 134 p.
A terrible plague has swept the world, leaving only a few survivors. English lad Neil, already numb with grief from the recent death of his family in a car accident, adapts relatively well to the empty, lonely new world. Setting out for London, he soon encounters other young survivors and scenes of misery, loneliness and madness.
In other words, John Christopher sleepwalks his way through a familiar young adult plot that never comes up with any particularly memorable scenes. Which is not to say Empty World isn’t a perfectly entertaining and enjoyable short read. There’s just nothing to distinguish it from his more famous apocalyptic works, or indeed any other number of post-apocalyptic pandemic stories.
