The Divine Invasion

Featuring virtual reality, parallel worlds, and interstellar travel, The Divine Invasion is the second novel in the VALIS trilogy by Philip K. Dick, the Hugo Award-winning author of The Man in the High Castle and Do Androids Dream of Electric Sheep? -- the basis for the film Blade Runner.

God is not dead, he has merely been exiled to an extraterrestrial planet. It is on this planet that Yah -- as this possible God is known -- meets Herb Asher and convinces him to help Yah return to Earth, which is itself under the control of the demonic Belial. To do this, Asher must shepherd a woman pregnant with Yah past the tight security of Earth.

Part science fiction adventure, part religious inquiry, The Divine Invasion questions just how much anyone really knows -- or really can know -- about the nature of reality and God.
