Half the mass-market paperbacks sold today are romance novels, and I'll bet you didn't know that “Romance novels are feminist documents written almost exclusively by women, for women, and are concerned with women: their relations in family, love and marriage, their place in society and the world, and their dreams for the future.”
H. W. Crocker's little book, Robert E. Lee on Leadership, is excellent. In it Crocker records this excerpt from a letter Lee wrote his wife...
about the books he did not want his son Rooney to read:
Let him never touch a novel. They print beauty more charming than nature, and describe happiness that never exists. They will teach him to sigh after that which has no reality, to despise the little good that is granted us in this world and to expect more than is given.
