A New York college student must rescue her love from a bizarre fate as evil threatens her world in this contemporary fantasy trilogy finale.

Three months have passed since Finn's beloved Jack traded his life for her sister's, walking into the underworld to take Lily's place. No one speaks of the Fata these days; everyone is pretending everything is normal.

But Finn cannot forget. And when she makes a daring odyssey into the world of the dead to bring Jack back, she inadvertently opens a dangerous fissure, giving the dead access to the true world.

With the lines between worlds more blurred than ever, Finn's friend Moth returns from Sombrus, the magical house once owned by Seth Lot, with terrible news: Something evil—something that resembles Jack—has escaped Sombrus. Now Fair Hollow is at risk from this Jack-like creature that will not stop until it gets what it wants . . . and it wants Finn.
