Heavier Than Air

Long in technology, but lacking fossil fuel, warfare in the future is quiet, personal, and deadly. Pilot John Young has survived long enough to see his two children entering a war. His son Eric will see engineless air combat in a matter of weeks, while his daughter Sara works deep in the electronic espionage center Section 12. Fate will force them together in dealing with a labyrinth of threats from their enemies to the north, and from spies operating deep within their own forces.
