I liked that in Cat's Cradle, which is the only book of his I read. It was interesting having the Ice-9 tracked throughout the story, even before we knew what it was or what it would do. At the same time, it was a little exhausting, and it made the narrative feel somehow shallow. While it was enjoyable reading, there was no point in the book where I actively felt a desire to know what would happen next. That's the problem with the lack of suspense, I guess.
