Blurb

The Divine Invasion is a BSFA Award nominated 1981 science fiction book by Philip K. Dick. It is the second book in the gnostic VALIS trilogy, and takes place in the indeterminate future, perhaps a century or more after VALIS. It was originally titled, "Valis Regained".
After the fall of Masada in 74 AD, God, or "Yah" is exiled from Earth and forced to take refuge in the CY30-CY30B star system. Meanwhile, the people of Earth are ruled by Belial, the spirit of darkness, but Yah is intent on reclaiming his creation.
