The Day of the Triffids
After most people in the world are blinded by an apparent meteor shower, an aggressive species of alien plant starts killing people.
What if a meteor shower left most of the world blind—and humanity at the mercy of mysterious carnivorous plants?
Bill Masen undergoes eye surgery and awakes the next morning in his hospital bed to find civilization collapsing. Wandering the city, he quickly realizes that surviving in this strange new world requires evading strangers and the seven-foot-tall plants known as triffids—plants that can walk and can kill a man with one quick lash of their poisonous stingers.
