New York: ROC / Penguin, (2006). The first book in this urban noir fantasy series. "Harper Blaine was your average small-time P.I. until a two-bit perp's savage assault left her dead for two minutes. When she comes to in the hospital, she sees things that can only be described as weird-shapes emerging from a foggy grey mist, snarling teeth, creatures roaring. But Harper's not crazy. Her "death" has made her a Greywalker- able to move between the human world and the mysterious cross-over zone where things that go bump in the night exist." 341 pp. ISBN: 0-45146107x.
