This book might be about women's lib or is it polygamy? Women need to play the main role in space travel and especially colonization. This SF series presents many issues to ponder and suggests some inventions needed for space travel. The series starts in today's world and through forced invention gets mankind into space colonization to save the human race. Most of the science presented is in some stage of development now. If you want to travel for months in space and then create a colony on an empty planet, you need more women than men. On a spaceship, or in a scientific laboratory, women can do what a man would do. The man may be better at leadership because women tend not to want to lead, but in reading this series you might agree with the author about the makeup of the crew. There are a number of morale issues.This is the 3rd book in the Ancient Destiny saga. Book 1 describes the threat to Earth and the SHIP that has taught the great scientists of Earth.
