Suzette brings Ellen to a small hut and Keats to a base on the edge of the village. That night, they are both visited by strange voices who invite them to the village pub, where they meet creatures they had never before thought existed, and are taken to a place that surpasses all imagination: the Netherworld, realm of the dead. Soon Keats and Ellen find themselves in a 17-year-old murder mystery, where the answers seem to only be found in the Netherworld, the land that can only be accessed from one place in the world, Doolin. To solve the crime and reveal Ellen's forgotten past, they each venture to the Netherworld as travelers, where Faerys and Folks alike await them.
