A review by annaswan
The Affinities, by Robert Charles Wilson

3.0

Wilson's usual plot is "The world is utterly transformed through some alien intervention, and people cope in various ways." That was done beautifully in _Spin_ and less well in others. This new plot is "Psychometric classification enables a new tribalism to emerge, and it turns out that tribalism is dangerous." It kept me turning pages, and made me wonder how OKCupid's friend-finding algorithm was shaping up these days, and whether people at Hogwarts ever changed Houses.
