Rhona has the divvy gift; she can see who is fertile and who is a cursed and outcast Shun. The people of the Deom depend on the divvys for survival, but it is a hard and brutal gift. As long as Rhona’s mother was alive, Rhona had followed the old ways, but now her mother is dead and Rhona is free. She has one last promise to fulfill: to find her mother’s friend Selina and help her.
Rhona finds Selina, only to become enmeshed in Selina’s vengeance against the body-stealing Rider, who has destroyed Selina’s son. Selina’s plan fails and she dies. Or does she? With the Rider pursuing her, Rhona flees across the land of Deo, desperate to keep her word and hide the one thing that might destroy the Rider. Rhona, her son Jak, her lover Matteo the Shun, and the strange girl called Aniles work together to discover the secrets of the Rider — and the true nature of the land of Deo.
