Query: The beginning of a long relationship-

I first read this book when I was 14, and literally never put it down. I remember by dad attempting to describe a puppeteer at dinner the night before, and I had been skeptical of concepts like impervious hulls, but the story weaves a diversity of elements together seamlessly. This year I stumbled into Niven again as an escape from law school reading, and find the science, narrative, and stories as compelling as ever. Its a pleasure to return to this book after so long, and I highly recommend it to any reader.
