On her 18th birthday, Lena Mattacascar decides to search for her father, who disappeared into the northern wilderness of Scree when Lena was young. Scree is inhabited by Peculiars, people whose unusual characteristics make them unacceptable to modern society. Lena wonders if her father is the source of her own extraordinary characteristics and if she, too, is Peculiar.
On the train she meets a young librarian, Jimson Quiggley, who is traveling to a town on the edge of Scree to work in the home and library of the inventor Mr. Beasley. The train is stopped by men being chased by the handsome young marshal Thomas Saltre. When Saltre learns who Lena’s father is, he convinces her to spy on Mr. Beasley and the strange folk who disappear into his home, Zephyr House. A daring escape in an aerocopter leads Lena into the wilds of Scree to confront her deepest fears.
