The Star Rover is a novel by American writer Jack London published in 1915 (published in the United Kingdom as The Jacket). It is science fiction, and involves both mysticism and reincarnation.A framing story is told in the first person by Darrell Standing, a university professor serving life imprisonment in San Quentin State Prison for murder. Prison officials try to break his spirit by means of a torture device called "the jacket," a canvas jacket which can be tightly laced so as to compress the whole body, inducing angina. Standing discovers how to withstand the torture by entering a kind of trance state, in which he walks among the stars and experiences portions of past lives.
