The novel “The Divine Invasion” by Philip K. Dick was published for the first time in 1981.
Emmanuel (Manny) Asher is virtually orphaned and “uncle” Elias Tate is the only one looking after him. His parents, Herb Asher and Rybys Romney, came from the colony of the planet CY30-CY30B but were involved in an accident that killed his mother and reduced his father into a coma before he was born. His delivery took place when she was already clinically dead.
At school, Manny meets Zina, a girl far too mature for her age who knows a lot about him. Everything is preparing for the final confrontation planned by Yah, the god banished from Earth who is trying to take back the world by defeating his opponent through Manny, his incarnation. To be able to do his work, hosever, Manny has to recover the memory lost following the accident.
