An interesting premise with a weak execution in a needlessly fragmented narrative. It wasn't a long novel but I felt that it would have either worked better as a short story or fleshed out in more depth as a longer novel.
Surprisingly, this book one a nebula award (or so the blurb on the cover claims) which just goes to show that winning an award is not always a good indicator of quality. Despite its award this is not one of Zelazny's well-remembered novels and, as far as I am concerned, for good reason; it's simply not that good. Particularly disappointing when you know the author is capable of so much better.
