First book in a trilogy.

Hardcopy includes excerpt from SleepWalker.

As the city sleeps in the early hours of September 10, 2001, the killer waits and watches, unaware of the cataclysm to come. Even the nightmare of 9/11 will not postpone his private reign of terror. Allison Taylor adores her adopted city, New York, loving every minute of the invigorating urban hustle. But on a bright and clear September morning, the familiar landscape around her is savagely altered--and in the midst of widespread chaos and fear, a woman living upstairs from her is found, brutally slaughtered and mutilated. For Allison . . . for her neighbor, James "Mack" MacKenna, desperately searching for news of his missing wife . . . for homicide detective Rocky Manzillo, hunting for a monster called "The Nightwatcher" amid the smoking ruins of a devastated city, this tragic day will hold a special horror. Because a different kind of terror has entered their lives . . . and it's coming to claim Allison Taylor as its next victim.
