Les Clans de la lune alphane

Clans of the Alphane Moon is a 1964 science fiction novel by American writer Philip K. Dick. It is based on his 1954 short story "Shell Game", first published in Galaxy Science Fiction magazine. War between Earth and insectoid-dominated Alpha III ended over a decade ago. (According to the novel, "Alphane" refers to the nearest star to our own system, Alpha Centauri). Some years after the end of hostilities, Earth intends to secure its now independent colony in the Alphane system, Alpha III M2. As a former satellite-based global psychiatric institution for colonists on other Alphane system worlds unable to cope with the stresses of colonisation, the inhabitants of Alpha III M2 have lived peacefully for years. But, under the pretence of a medical mission, Earth intends to take their colony back.
