This saga begins with the Memory of Earh and the tale of Nafai and his family in their struggle on the planet Harmony. The planet is controlled by a computer known as the Oversoul, who has been secretly breeding people in order to bring them back to Earth to repopulate it. This is an excellent story which builds up deep, rich characters and builds a strong set of relationships between characters. Powerful foreshadowing can be noticed in this book. What will Nafai and his family choose to do? Will they follow the will of the Oversoul and lead themselves out of their great city, or will they stay and Nafais's older brothers, Elemark and Mebbekew wish to do?
