This book is structured in parts, with each part starting with some time with a small girl who will start everything in the rest of the book, and then goes on to chapters which alternate viewpoints from Campion and Purslane. Campion and Purslane are two of the thousand "shatterlings" -- clones of the small girl who circuit space making money and learning things. The two of them are consorting, which is not allowed, and are late for the shatterlings reunion, but when they get there, the reunion has been destroyed. By whom? Is there a traitor? How can they fix what happened?
This was really interesting and other than the voices problem, I would like it a lot.
