Query: Wait for a used copy of the paperback edition.

The book is dreary and shallow and certainly not up to the level of his previous book about the living dealing with the dead: Psychlone. Additionally, this book gives no hint of how good Greg Bear can be, and was in Eon, Eternity, Blood Music, Moving Mars, The Forge of God, and Anvil of Stars. It was a waste of my time and money, though I've read everything Greg Bear has written and will continue to do so hoping for a return of the storytelling skill he showed in his early works. If this is your first exposure to Greg Bear and you were disappointed try one of the books mentioned previously. He was a good storyteller once but seems to have lost it lately.
