This book takes place generations after the last book which makes it both an outlier of the five books and a hell of a lot more confusing than it need be. As it has been generations, the stories of the first four novels have become legends and the legends have become myth and are religious in their overtone.
I was pleased however that Shedemi, the character I came to love over the last two books remained alive in the cloak of the Starmaster spending hundreds of years asleep and waking up to tend her garden of earth. Shedemi has finally decided that she needs to return to the planet and participate in life again, she can no longer remain solely as the gardener of earth. Her humanity has decided that she needs to interact with people and so she opens a school and causes all sorts of chaos.
