The Ganymede Takeover
The Ganymede Takeover is a 1967 science fiction novel by American writers Philip K. Dick and Ray Nelson. It is an alien invasion novel, and similar to Dick's earlier solo novel The Game-Players of Titan. Dick later admitted that The Ganymede Takeover was originally going to be a sequel to his alternate history novel The Man in the High Castle with the Japanese occupying the United States not Ganymede.    

Earth has been taken over by a strange alien force - creatures whose instinct for survival overrides any human resistance.
Then a vital weapon - with the powre of electronically warping the mind - falls into the hands of a terrorist group still strong enough to oppose the aliens. A weapon so powerful that it cannot be controlled.
**The control of Earth is in the balance - and the balance is a terrifyingly precarious one.**

Philip Kindred Dick was an American novelist, short story writer, and essayist whose published work during his lifetime was almost entirely in the science fiction genre. Dick explored sociological, political and metaphysical themes in novels dominated by monopolistic corporations, authoritarian governments, and altered states. In his later works, Dick's thematic focus strongly reflected his personal interest in metaphysics and theology. He often drew upon his own life experiences and addressed the nature of drug abuse, paranoia and schizophrenia, and transcendental experiences in novels such as A Scanner Darkly and VALIS.
