Publisher's Synopsis
For two hundred years, the Selkies have kept themselves separate from those who live on the land. But now, the Selkies need allies or they will be crushed by their ancient enemies, the Finfolk. What Jacob and Ophelia find in the eighth room uncovers a mystery that dates to Darkbrook's beginnings, and might save the Selkies from extinction. With the help of the youngest member of the Wild Hunt, they must foil the Finfolk who desire the Selkie's destruction... or die trying.
