The Star Rover, also known as The Jacket, was published in 1915 and is one of Jack London's later novels. This work is a blend of science fiction, adventure, and philosophical exploration.

The story follows Darrell Standing, an inmate in a brutal California prison who is subjected to the cruel punishment of solitary confinement, known as "the jacket." While in this jacket-a straitjacket that confines him in complete darkness and immobility-Standing experiences a series of vivid and surreal past-life regressions. Through these regressions, he relives various lives across different times and cultures, each offering insights into different aspects of human existence and experience.

As Standing journeys through these past lives, he reflects on themes of freedom, the nature of the self, and the impact of individual actions across time. The novel combines London's interest in the harsh realities of human experience with his fascination with reincarnation and metaphysical concepts.

The Star Rover is notable for its innovative narrative structure and philosophical depth, as it grapples with existential questions and the struggle for personal liberation in the face of oppressive forces.
