Miss Margaret Ridpath and the Dismantling of the Universe

From the back cover: "Miss Margaret Ridpath, raised in a midwest world of rigid proprieties and repressed passions . . . learning of sensual love in the arms of another woman's husband . . . facing the searing trials of life with courage and pride . . . and moving toward confrontation with the forces of sick violence and anarchic sexuality of an America grown savage in the 70's." "Robertson has achieved his most full-blooded triumph in the creation of an unforgettable heroine swept up in the floodtide of her desire and the tempestuous changes of our time. The best of Robertson's novels yet -- expertly constructed, immensely readable, utterly convincing, with a pulse-racing climax." So there. Read it.
