As was told in the book And What of Earth?, a species of symbiotic aliens has appointed a human, Jennifer Hodges, the new Mother of the Wakira. She now finds herself on the homeworld of the Wakiran Empire, alone and cut off from her friends and family in Nebraska, with only her alien mate and her personal assistant to support her, and to help her transition from being a barbarian Terran to the second-most powerful person in this part of the galaxy. While many of her "children" love and obey her, she faces opposition from the very people she needs to help her in her new role -- that of the protector of the Empire. She is keenly aware of the prophetic vision she had when the symbiote took residence in her mind. Billions of people will die because she won't be ready. But instead of helping to prevent that devastation, Jennifer's predecessor works to drive the one she considers to be an interloper back to her barbarian planet. Jennifer is left having to make life-or-death decisions without any help and with insufficient information. Will another insurrection bring death and destruction to the Empire, or can Jennifer somehow prevent the prophesied disaster?
This book continues from the novel And What of Earth? While it isn't necessary to read the earlier volume to understand what is going on, it will help with fully understanding the scenario, and will give the main characters additional depth.
