Philip Wylie’s book, ‘The Disappearance’, might interest you; from WikiPedia: His novel The Disappearance (1951) is about what happens when everyone wakes up one day and finds that all members of the opposite sex are missing (all the men have to get along without women, and vice versa). The book delves into the double standards between men and women that existed prior the woman’s movement of the 1970s, exploring the nature of the relationship between men and women and the issues of women’s rights and homosexuality.
Actually there’s a bunch of sources wandering around this one, “The Disappearance” being one of them. I did a storyline some years back in which everyone who wasnt white vanished… except they hadnt: the white people just couldnt see them. One of my more subtle tales. LOL
