This is a book my wife read as a child, and I read it myself after we got together - as a lover of apocalyptic fiction, I loved it, and I felt it was time for another read after I just read "The Death of Grass".
Apparently this is one of no less than eleven post-apocalyptic novels John Christopher wrote for the young adult market, so I'm certainly keen to find and read more. This one is about a boy called Neil Miller, who has to go and live with his grandparents in a sleepy village after the rest of his family die in a car accident. Shortly after this, a disease known as the Calcutta Plague sweeps across the world, causing premature aging and death - only the young are spared.
The only-the-young-survive trope seems done to death in YA post-apocalyptic fiction and it feels like bit of a contrived plot device sometimes, but I can forgive it here. I've only read two of Christopher's novels, but he's a master of the type of writing I love. This is a short book I ploughed through very quickly, and not a huge amount really happens, but it's absolutely dripping with atmosphere and some haunting images that will live with you. They're beautifully described in simple, concise prose - there's nothing there that doesn't need to be, it all just builds up powerful pictures as you read.
Neil leaves his grandparents' home and ends up in London, where he comes across a few survivors. It would be a bit spoilery to go into too much detail about what happens when he meets them, but his interactions with them are beautifully described, and the (small) cast of characters feels very credible. There's only one dramatic incident really, right at the end, and the ending is quite abrupt but full of possibility.
The book was written in 1977, and it feels somewhat more contemporary than "The Death of Grass", from 21 years earlier, but it's still quite old-fashioned in places. You'd do yourself a favour in remembering that as you read - I get the impression that Christopher's attitude towards women was somewhat unenlightened. It's a minor criticism, though - if you enjoy an atmospheric, haunting and memorable read, there's a lot to love here.
