A lively and inventive story built upon historical facts and reasonable suppositions. My enjoyment was somewhat marred by an excessive number of scientific and engineering boners. For example, light is reflected, not refracted from low lying clouds, freeze-dried materials are rehydrated, not hydrogenated, radio waves do not propagate through sea water and cannot possibly be used to communicate with an underwater exploratory vehicle.
Jeff Cummings often blunders in his pronunciations of both scientific words such as helical, and of the names of many well known scientists.
The first three or four examples of computer hacking achieved by fooling people into divulging seemingly innocent information were interesting, but the rest of the book is more of the same. I couldn't force myself to listen to more than the first third.
This well researched book added much human interest and background to many of the scientific and technological developments behind electricity and electronics. The author's overzealous attempts to simplify generated too many totally inappropriate analogies and lead me to suspect that neither the author nor the editor ever took even high school physics. Nonetheless, I learned much from the book and even more from following up on interesting leads mentioned in the book or omitted from the book (e.g. De Forest's invention of the vacuum tube).
