Death needs a mortal's help to bring her rebellious daughters back, but not just any mortal will do. Only someone who has experienced the three realms of the sisters can hope to meet their challenges and send them back through the gates of death. Jake Rodden is a war veteran who has been suicidal since the loss of his wife and young daughter, but he finds hope in an unusual place—the journals of a WWI field nurse named Sybil Etienne. Some say Sybil earned an eternal reward from Death, after Sybil found a way to return Death's daughters to her. The ancient Assyrian myth of the 'Three Sisters' tells of how the daughters of Death each have a realm on the border between life and death, where they collect their power as mortals face death. The first sister consumes grief; the second despair, and the third sister wants bravery. If the sisters grow too powerful, they will threaten the balance between life and death. Jake will have to learn from Sybil's journals how to track down the three sisters in dreams of the past, where everything that is most precious to him lies.
