Brave New World
Free love, birth control, test tube baby factories, cloning, mutants, and sex, sex, sex. There are good reasons to have your mature students read this book, but you must do YOUR homework and read it first.
Huxley, writing during the giddy early days of the eugenics movement, has written a remarkable novel. His story portrays that movement's ideas taken to their logical consequences. There is a complete disconnect between sex and procreation. Sex is STRICTLY for pleasure (not even for unity). Babies are 'decanted' in factories by impressive scientific processes.
