Marianne O’Hara grew up in New New York, one of multiple “Worlds”, large orbital habitats supporting hundreds of thousands of people. The Worlds are varied, socially liberal, and very different from the less progressive Earth. Marianne is sent on a one year study trip to Earth, to immerse herself in Earth culture and society. While in “Old” New York, enrolled at NYU, culture clash sets in quickly, and she is exposed to the awful realities of American society. The larger story involves how the Worlds are inexorably moving towards independence. They provide energy and materials to Earth, mostly America, in return for specialised goods, and hydrogen. The discovery of hydrogen deposits in space precipitates the problem, as Earth powers see their influence slipping away.
This book has aged badly, mostly due to its depiction of life in New York and other places on Earth. This is a New York stuck in the seventies, with rampant violent crime, prostitution around Times Square, muggings and rapes. In contrast, O’Hara’s “free love” upbringing leans heavily on late 60s tropes. The technology is all tapes and recordings and long distance phone calls. The development of nations in the world is very much seen from a late seventies lens, for example the merger of the Soviet Union and the People’s Republic of China.
The characters are well fleshed out, especially the protagonist. Seeing this Earth from a foreigner’s lens paints an ugly picture, which is presumably what Mr. Haldeman intended. The use of narrative devices such as diary entries, phone call transcripts and letters is interesting but can sometimes feel disjointed.
