When a freak cosmic event renders most of the Earth's population blind, Bill Masen is one of the lucky few to retain his sight. The London he walks is crammed with groups of men and women needing help, some ready to prey on those who can still see. But another menace stalks blind and sighted alike. With nobody to stop their spread the Triffids, mobile plants with lethal stingers and carnivorous appetites, seem set to take control.The Day of the Triffids is perhaps the most famous catastrophe novel of the twentieth century and its startling imagery of desolate streets and lurching, lethal plant life retains its power to haunt today.
