One-child rule & female infanticide unbalances the population, forcing one hundred thirty million men to live as BARE BRANCHES. Chinese scientists race social upheaval.

Cai Ling Luk was raised a princess by Chinese aristocrats whose fathers fled China when Mao Zedong defeated the nationalists in 1949. Her aloof parents allow her to choose her college. She moves to America and changes her name to Sally Luck. And then, angry over pain and the foolishness of men, Sally choses hysterectomy as elective surgery, and then spends the rest of her life regretting it--until technology and global politics intervene.
