In the mid-1970s, after a life in government service, which was shadowy in its depths, Ted Wertime built a fortress-like house on a mountaintop in south-central Pennsylvania. He had forged for himself a secondary career as a highly respected historian of ancient science and technology, and was convinced that it was his fate to lead a sweeping revolution that would cleanse the United States of energy abuse, political corruption, and an odd assortment of social ills. His "citadel" would serve as his revolutionary headquarters. He, his wife, and Joan, the last and most troubled of his succession of mistresses, lived in the house together in a bizarre menage a trois. His dream was to recruit his four sons to take part in his cause.

The author, Richard Wertime, is the second-oldest son. Citadel on the Mountain is the story of his struggle to escape from a domineering and, at times, hypnotizing father who sought to control the sexual and professional lives of his offspring.
