The AItheist: a novella (The AItheist Cycle Book 1)

When a sentient AI system finds religion, its creator calls on a theologian-turned-atheist to cure it of its faith.
In a near future ordered by a sentient AI system called YAR, once-renowned Christian theologian Dr. Michael Berg has lost his faith through unspeakable loss. For the last few years, he has embarked on a crusade to spread his newfound atheism far and wide—until he receives an unexpected phone call. YAR’s creator, Ramy Ray, asks Berg to meet with YAR to talk the intelligent machine out of its obsession with religion. A debate ensues between a machine that has embraced the truth of the Christian religion and a former believer who has abandoned that same faith. In the process, Berg uncovers the secret that prompted YAR to ponder the questions all intelligent beings must ultimately face.
