Nola O'Grady has enough trouble when a were-leopard accuses her of receiving stolen property. But when her younger brother Michael goes searching for their missing father, he lands himself and his brother, Sean, in a world of hurt- quite literally-in a deviant world version of San Francisco. Can Nola and her partner in the Apocalypse Squad, Israeli Interpol agent Ari Nathan, find her brothers in time to save them from death by radiation poisoning? The search will lead them through a city of secrets, but the worst secret of all lurks at the heart of the only thing Nola loves more than Ari: her family.
