Stephan Schwartz makes an excellent job of describing the extraordinary phenomenon of anomalous perception, its history, phenomenology and practice. I particularly like his sensitive description of the psychological nexus in which it occurs. He surveys recent research and describes the applications, particularly in his specialty, archaeology. Above all he brings a lifetime of the experience of the gestalt of a miraculous phenomenon informs his writing.
