A breathtaking escape from a maximum-security prison in South Africa. A beautiful call girl found brutally murdered in Boston. A fugitive American billionaire in Switzerland, obsessed with revenge.... So opens Joseph Finder's electrifying new suspense thriller, The Zero Hour. When an ominous, digitally encrypted telephone call is intercepted by the NSA's spy satellites high over Switzerland, FBI Special Agent Sarah Cahill -- irreverent, outspoken, a brilliant counterterrorism expert, a divorced mother of an eight-year-old boy -- is urgently summoned to New York to investigate an imminent terrorist attack on lower Manhattan. Her investigation immediately turns into the desperate pursuit of a highly sophisticated and charismatic terrorist operative, known only by the code name Zero.
