Laszlo is an eight-hundred-year-old demon and Hell's least productive Curse Keeper. From his office beneath Midtown, he oversees the Drakeford Curse, which involves a pathetic family upstate and a mysterious black monolith. Maggie Drakeford is a nineteen-year-old Curse Bearer. All she's ever known is the dreary corner of the Catskills where the Drakeford Curse has devoured her father's humanity and is rapidly laying claim to her own. The future looks hopeless, until Laszlo appears at the Drakeford farmhouse one October night and informs them that they have only six days to break the spell before it becomes permanent. Thus begins a breakneck international adventure that takes our unlikely duo from a hot dog stand in Central Park to the mountains of Liechtenstein.
