As a reader for many decades, the total number of books I’ve read has to be much higher than the places visited by the most travelled characters of this engaging book. This is the most FUN read I remember--Agatha Christiesque (with tech) and mystery, murder, red herrings, and surprises. As a lower-level of the community featured—though like the character Jack, with a number that could make me a potential victim—I recognized and laughed, agonized, empathized, and suffered with the challenges of travel the characters (some of whom I also recognized) encounter, while remembering visits to many obscure places and dreaming of visiting others. While I wonder if non-travelers would have the same reaction to the settings, the over-the-top characters and plot would surely engage any reader, and perhaps encourage some to travel or at least google and imagine remote and exotic locations.
