A mysterious vigilante group hunts down celebrities in a ruthless effort to promote equality, in this harrowing thriller by the author of My Favorite Terrible Thing.

In front of a sold-out crowd at Madison Square Garden, a pop star is kidnapped by a new vigilante group called the Nomen. They leave behind a chilling manifesto leveled against the cult of celebrity, and the names of forty-nine other rising stars about to disappear forever. Bestselling author Fiona Hart is on the list.

One by one, targets vanish without a trace. Fiona can’t shake the feeling that her every move—on a public street or even in the privacy of her own apartment—is being watched. Though the world may be gripped by fear, Fiona refuses to let it destroy her. Then her friend, popular shoe designer Gwen Gordon, goes among the missing. And time is running out for Fiona.

As she unravels the Nomen’s true and twisted motivations, the last celebrity in hiding will risk anything to save herself and those she loves.
