The Triffids are actually a side concern in this book. While they are a threat to those involved, they are also just a nuisance. The story is about people and how they react and or cope with a disaster that could not be anticipated.
The Triffids have spread around the world and nobody knows where they came from. The best thing about them is they secret and oil that is profitable, the worst is that they are able to use their roots to actually walk and use a stinger to release a poison when they strike someone.
We then have the earth pass through a comet tail which creates a meteor shower that is viewed by people around the world. The next day those who saw it are blind.
The story follows those who are sighted and what they endure trying to survive in a world that is fast falling into chaos. Roaming gangs of the sighted, blind people being used as slaves, and the triffids taking advantage of the situation.
There are no major scares or high emotion, just good story telling.
