Summary: Uninteresting people act petty and crappy... on a large scale.

If I want to read about people becoming savages, I'll read Lord of the Flies. Social structures developing in isolation? Hugh Howey's Silo series. White collar psychotics? American Psycho.

I suppose this book just wasn't for me. It did have some memorable imagery, but that came up a bit short when I had so little interest in the characters or story.
