After fleeing Earth to the planet Kareen, thief and murderer John Carmody is taken in by two Catholic missionaries who order him on a covert fact-finding mission to the Temple of Boonta on the eve of an annual ritual known as the Night of Light.

Most Kareenans take sedatives to ensure that they sleep during the chaotic and savage Night. To remain awake is to be subjected to torturous hallucinations, to lose one’s sanity, and potentially, to be murdered or commit suicide.

Fearless and irreverent, Carmody mocks all religions, until he defies regulations and remains awake during the Night in an attempt to assassinate a god incarnate named Yess. According to Kareenan beliefs, the goddess Boonta has two sons, the benevolent Yess and the evil Algul, each of whom are reborn through the ages and take turns ruling Kareen.

As me makes his way through the streets to the temple where Yess has concealed himself for the Night, Carmody is confronted by bizarre, disturbing visions that eventually compel him to renounce his old life and convert to Catholicism.

Years later, after returning to Earth and undergoing rehabilitation, Carmody enters the priesthood and is ordered by the Church to return to Kareen and dissuade the latest incarnation of Yess from sending missionaries to spread Boontism to other worlds. However, vestiges of Carmody’s old life reemerge as the Night of Light is once again nearly upon Kareen…

Strong in both plot and character arc, Night of Light is yet another captivating, original, and wildly imaginative example of Philip Jose Farmer’s propensity for using science fiction as a milieu to explore and question long-established religious beliefs. This is also evidenced by some of his other works, such as Inside Outside and the Riverworld series.
