The Star Fraction
The Star Fraction is a science fiction novel by Scottish writer Ken MacLeod, his first one, published in 1995. The major themes are radical political thinking, a functional anarchist microstate, oppression, and revolution. The action takes place in a balkanized UK, about halfway into the 21st century. The novel was nominated for the Arthur C. Clarke Award in 1996. Plot summary. The world is controlled by the US/UN, a sort of semi-benign meta-dictatorship which does not rule directly but enforces a series of basic laws on a vast number of microstates, many of which  are in a near-constant state of low-intensity warfare. Among the laws enforced on them is a prohibition on certain directions of research, such as intelligence augmentation or artificial intelligence. Precisely what is prohibited is of course secret, and as violation of the prohibitions will result in the swift and efficient death of everyone directly involved, scientific research is a dangerous proposition at best. The main characters (a Trotskyist mercenary, a libertarian teenager from a fundamentalist microstate, and an idealistic scientist) find themselves caught up at the centre of a global revolution against the US/UN. The revolution was  planned and partially automated by financial software, and it was set to break out after a certain set of conditions are met. The stakes are raised at the end of the book, when it is revealed that the autonomous financial software has evolved into an intelligent form, which might cause the paranoid US/UN to make a "clean break" with Earth, knocking the planet back to the Stone Age with the orbital defence lasers. Series. "The Star Fraction" is the first book of two series: one is a trilogy, and ends in "The Cassini Division" with a war between humans  and a society of uploads inhabiting the massively re-engineered Jupiter; the other consists of "The Star Fraction" and "The Sky Road", and occupies a parallel universe, in which one of the main characters makes a different decision at the end of the first novel, which results in a very different, catastrophic outcome. Reception. Gideon Kibblewhite reviewed "The Star Fraction" for "Arcane" magazine, rating it a 5 out of 10 overall. Kibblewhite comments that "Pluses of the book [...] include a clever and well-described future culture that might be fun to play in (its institutions and factions have armed militia  who act as legal terrorists in a game) and a great set of baddies who operate from cyberspace."
