I got a real kick out of the fact that the very first book that I read on my Kindle was about a guy with a magic Kindle. I had no idea when I downloaded the book. All I knew was that here was a King book that I had never read or even heard of for that matter.
Not King's best work but not his worst either (I recently read Full Dark, No Stars...and that's how I would rate it: No Stars!).

I bought this book in hardback when first published and reread it recently for the fourth or fifth time. It's always enjoyable. There's just something about the idea of living a life in near freefall that is very appealing. I find the cover art (my favorite of ANY book) fascinating. The story and characters are fine but it's the "Smoke Ring" it'self that's the main character.
I've always appreciated the work that Larry Niven puts in to get the physics correct before he goes any further.
