Dilys is a devoted member of a terribly English cult: The Panacea Society, populated almost entirely by virtuous single ladies. When she strikes up a friendship with Grace, a new recruit, God finally seems to be smiling upon her. The friends become closer as they wait for the Lord to return to their very own Garden of Eden, and Dilys feels she has found the right path at last. But Dilys is wary of their leader’s zealotry and suspicious of those who would seem to influence her for their own ends. As her feelings for Grace bud and bloom, the Society around her begins to crumble. Faith is supplanted by doubt as both women come to question what is true and fear what is real.
