What those of you considering reading this book should be concerned with is the fact that this is the third book in a trilogy. I had not read the first two and that kept me from truly loosing myself in the narrative more than the technology gaps.

The plot is pretty typical of the Nora Roberts oeuvre. There are three blue diamonds, known collectively as the Stars of Mithra. There is a string of murders which take place in the search for these priceless diamonds, before they enter the Smithsonian Institute. In pursuit of the perpetrators of these crimes Detective Seth Buchanan finds himself charged with solving the murder of Grace Fontaine. Who shows up very much alive and becomes something Seth cannot keep a professional distance from.
