Query: Space program thriller

Richard Reid obviously knows his way around NASA--from the cool bravery of our Astronauts to the NASA scientists and engineers in the labs, to the administrators who roam the NASA corridors.From the opening chapter which features a Saturn rocket failure, and a "negative return" that ends in a spectacular crash, to the search for the mole who sabotaged the flight, Richard Reid maintains the pace and suspense of a great techno-thriller. His novel gives an insider's look at how espionage, infighting between scientists and bureaucrats and power politics can affect our space program.Readers who revel in technology will be satisfied by the authenticity of the science, but Reid never lets technology override the human factors that drive our Astronauts and NASA in their quest to conquer the frontier of Space.
