As he sails into Moon City, a floating community of anarchists in the North Pacific, Doctor Paul Bronski is greeted by a sign: "We owe you nothing." A refugee from the economically and politically repressed continent, Bronski meets harbormaster Grace; from this attractive rebel he learns about a truly free way of life-and about committed love. Targets of a misguided counterintelligence operation, Paul and Grace must outsmart and outrun the mighty espionage organization, both on the waters of the Pacific and in the mountains of Panama. They confront the brute power with courage and unorthodox thinking-but is that enough to keep the couple-and their ideals-alive and "off the leash"?
