An interesting concept that quickly descends into dreck. I expected better from a couple of genre masters. The writing style wanders, a common thing when more than one author is involved. Rather than a coherent science fiction story, this book lurches between sections of story, science, and case studies that with work, could have been turned into a novel.
The authors use wormholes as a device that enables universal surveillance, including reaching into the past. This could have been terribly interesting; instead, the choices the authors made varied between boring, pandering, and predictable. Religion is trashed, but in the end, all the authors can think up is to have the great god science engineer resurrection for everyone.
