The mesmerizing conclusion to the Night and Nothing series—a blending of Scottish fairy tale and modern magic that is part Buffy the Vampire Slayer and part Alice in Wonderland—finds Finn fighting against the land of the dead.

When her beloved Jack disappears, Finn vows to find him—even if it means a daring odyssey into the land of the dead. But saving Jack comes at a terrible price: a dangerous fissure has opened, giving the dead access to the true world.

The lines between worlds are more blurred than ever. Finn’s sister, Lily, recently returned from the Ghostlands, seems to bear no scars from her time there. But then their friend Moth returns from Sombrus, the magical house once owned by Seth Lot, bearing shocking news. Something evil—a fearsome creature bearing a striking resemblance to Jack—has escaped Sombrus and is now stalking Fair Hollow, killing everyone it encounters, transforming them into terrifying Jacks and Jills and recruiting the Unseelie.

It will not stop until it gets what it wants . . .

Finn.
