Sleepwalker (Nightwatcher‪)‬

Ten years after the catastrophe, a great fallen city has risen again. Ten years after, a horror begins anew . . . or never truly ended. The nightmare of 9/11 is a distant but still painful memory for Allison Taylor MacKenna-now married to Mack and living in a quiet Westchester suburb. She has moved on with her life ten years after barely escaping death at the hands of New York's Nightwatcher serial killer. The monster is dead, having recently committed suicide in his prison cell, but something is terribly wrong. Mack has started sleepwalking, with no recollection of where his nighttime excursions are taking him. And here, north of the city, more women are being savagely murdered, their bodies bearing the Nightwatcher's unmistakable signature. Suddenly Allison must confront a devastating truth: her life is in jeopardy once again . . . and quite possibly from the man she trusts and loves.
