When Bill Masen wakes up blindfolded in hospital there is a bitter irony in his situation. Carefully removing his bandages, he realizes that he is the only person who can see: everyone else, doctors and patients alike, have been blinded by a meteor shower. Now, with civilization in chaos, the triffids - huge, venomous, large-rooted plants able to walk, feeding on human flesh - can have their day. The Day of the Triffids, published in 1951, expresses many of the political concerns of its time: the Cold War, the fear of biological experimentation and the man-made apocalypse. However, with its terrifyingly believable insights into the genetic modification of plants, the book is more relevant today than ever before.
