Summary: A virus kills nearly everyone, society collapses, but some survive.
Station Eleven has had a lot of hype. It has been short listed for a ton of awards, John Wilson (from Books and Culture) loved it, a lot of people that I know really liked it.
And I thought it was ok. A solid, but not earth-shattering end of the world novel.
There are a lot of characters and none of them are really the main character. Station Eleven moves back and forth between characters and from before the fall of civilization to after the fall. By the end, there is at least the hint of a complete story, connecting all the various characters and times.
The fall is caused by a swine flu variant called ‘The Georgian Flu’. In a matter of hours from contamination, with basic flu symptoms, 199 out of 200 people die. Within a few days complete panic has hit. Within a few weeks civilization has completely collapsed. The electric grid goes down, transportation stops because no one can get gas (and what gas is available goes bad in a few years.) The sheer size of the devastation (and the fear of a reoccurrence of the outbreak) keeps people in small groups and afraid of strangers.
