A satisfying conclusion to this series (essentially a trilogy and and out-of-sequence prequel). As in the first book, Lina and Doon take on a quest for better quality of life based on an uninterpretable document from the Builders. Though they encounter obstacles and belligerents, one can't really say they meet enemies. A hallmark of this series is that ultimately most people, even those in opposition, are rendered benign or ineffective over the course of the story, making this a good series for people who like dystopian themes but not the distress of a true dystopia.
