Overall, there are only tenuous connections between the stories, so it's hard to evaluate it as a novel. Oh sure, there is the telltale birthmark (I half-typed bookmark) that lets you identify certain souls. And certain themes reappear, mainly about human beings being schmucks to each other. Another theme or element I noticed was that each story involves a stolen book, or stolen papers, or (for the future) unauthorized data access.
Maybe my own genre preference is leaking out, but I found the speculative stories to be quite excellent, with well-realized future worlds. But all of the stories have their good points, even if I don't see them adding that much to each other, or the interleaving to add very much to the whole. But that one theme is well worth repeating, so I will.
Don't be schmucks to each other.
