The novel depicts a matriarchal society where men are used just for work and are considered only as a necessary means for having daughters. Sons are highly undervalued, and for this reason advances in science will soon make it possible to select gender in a lab. Also, technology is going to be able to produce machines that would do all the work that males do, so there would be no man left around. Many women wonder if it's time to take the leap towards a New Humanity.
However, someone comes from the future seeking answers, with even more intriguing questions. Where did this society come from? Why do they know nothing about their origins? What happened to the Old Humanity?
Mysteries will unfold in succession, and just when things seem to be clearing up, new, even deeper questions will arise. Finally, to understand what has happened, another journey through time will be necessary, back to the very dawn of Humanity. The explanation will be completely unexpected and will surprise many.
