Earth Revisited
 The novel delivers the story of Herbert Atheron in a first-person narrative. In 1892 he is a successful businessman, married, the father of a son and daughter. Though not yet 50 years old, he has contracted a fatal illness; at the start of the book, he is dying. He re-evaluates his life, to reach a grim conclusion: he feels that he has wasted his life by concentrating on business and neglecting the personal and familial matters that count most. He especially regrets the loss of his first love, a woman named Theresa, who died young after he abandoned her. On his deathbed, he feels himself "alone in the vast vacuity of space, a naked, shivering soul. A deep darkness of horror engulfed me. I could endure no more." When he regains consciousness, he finds himself in the body of a 27-year-old man named Harold Amesbury. He discovers that it is now a hundred years later; Amesbury has been ill and delirious for three months. His fiancée, Helen Newcome, is overjoyed at his recovery &mdash; but stunned when he reveals his identity as Atherton. Helen determines to nurse Herbert/Harold back to mental health. She leads him out into the world, where he confronts the vast changes of the intervening century, and beholds the "bewildering magnificence and beauty" &mdash; of Brooklyn in 1992. Helen Newcome brings the protagonist to her inventor father; together, the two Newcomes guide the confused time traveller in the realities of 1992. Society has enjoyed vast improvement in the intervening century: the city of Columbia, formerly New York, is cleaner, better organized, more peaceful, healthier, and generally better than before. Electrification and mechanization have brought widespread prosperity, and the extremes of wealth and poverty have been levelled. Government has assumed more responsibility: all land is owned by the state, and people lease the sites of their palatial houses. Newcome the inventor concentrates on improving food production; he receives a stipend from the state, and his inventions go to benefit society as a whole. Brooks does not dwell on the larger political organization of society, though he indicates the world is dominated by the United States of America and a "United States of Europe." War is a thing of the past. Brooks blends the technical and the spiritual: when Newcome shows the protagonist the new "harmonic telegraph," Atherton/Amesbury speculates about the possibilities of both radio and telepathy. The second half of the book is dominated by spiritual matters. The protagonist has a rough adjustment to his strange situation, and obsesses over his lost Theresa. Helen Newcome grows distressed at her limited ability to help her fiancé, and leaves for a trip abroad. Atherton/Amesbury boards with a widow and her children. The daughter of the house, Irene, was used as an experimental subject in hypnotism by her late physician father; she is a spontaneous medium and clairvoyant. Irene leads the protagonist on an aerial journey to the now-lush Sahara, where he is re-united with Helen. Through psychic visions, the two come to understand that Helen is the lost Theresa reincarnated. They are happily married in the end.
