On All Hallows' Eve, the barrier between the living and the dead is thinnest.

Nicholas Harwood has inherited an unusual job—keeping the dead quiet. For several nights before All Hallows' Eve, he pours a potion derived from a family recipe on the graves of the late residents of Dante's Hollow to keep the dead from walking. So far, he's been successful. But something—in addition to snow—is in the wind, and he can't stop it alone. Nicholas and his unlikely group of companions—a druid sorcerer, a witch, and a ghost or two—are locked in a power struggle with rogue supernatural powers intent on unleashing great evil.
