From her cell in a mysterious convent, a lower member of the Sacred Sisterhood dreams of ascending to the ranks of the Enlightened. Outside, cities are submerged underwater, electricity and the internet are nonexistent, and survivors fight and forage in a cruel, barren landscape. A stranger makes her way past the convent walls, and as the two women grow closer, the narrator is increasingly haunted by questions about her own past, the environmental future, and her present life inside the convent. How did she get to the Sacred Sisterhood? Why can't she remember her life before? And what really happens when a woman is chosen as one of the Enlightened?
