Two thousand years ago, the Pestis Disaster swept across the land and corrupted everything that lived in it. Those who chose to remain on the dying earth built a temple to give their survival structure and meaning: Saint Sheol of the Underworld. The narrator arrives as a trainee priest, struggling in an unfamiliar place, until a dream brings the face of someone she recognizes in the form of an angel. Six young women stand at the threshold of a disaster that has not arrived yet. In the deepest rooms of the temple are fear and miracles, love and longing. Having looked into the darkest darkness the world has to offer, the only thing ahead is an overwhelming light. The question is whose wings appeared in that dream.
