In the twenty-sixth century, humanity is no longer the dominant species. The cruel and mysterious Fair Folk stalk the lands. The humans who remain live in fear in isolated communities. One of these humans is Owen Pasha, a biomancer who has dedicated his life to understanding what drives the Fair Folk. His thirst for knowledge may cost him all he holds dear. The ascetic superhumans known as the Immortals claim to be all that stands between humanity and destruction. When Inanna, an Immortal in training, tries to escape her sheltered life in the monastery, she must question everything she has been taught about the world and her place in it. Owen and Inanna’s search for answers can only lead them to the Stone Forest, an ancient city haunted by the Fair Folk, and to the horrifying truths that await them within.
