New Yorkers aren't easily intimidated, but someone is doing their best to scare them, badly. Why? After two crippling high-tech attacks, the entire city is on edge. Detective Michael Bennett, along with his old pal, the FBI's Emily Parker, has to catch the shadowy criminals who claim responsibility -- but they're as good at concealing their identities as they are at wreaking havoc. When a shocking murder in broad daylight points to killers both skilled and cold-blooded, Bennett begins to suspect that these mysterious events are just the prelude to the biggest threat of all. Soon he's racing against the clock, and against the most destructive enemy he's faced yet, to save his beloved New York-- before it's lights-out for the city that never sleeps. -- Puiblisher's description.
