One thing long plane rides are good for is chewing through a big fat book. That's how I finished Chasm City during the recent Chatanooga trip. I enjoyed it, and plan to read Redemption Ark sometime in the next few months. About the only thing negative I can say is that the plot was a bit more predictable than Revelation Space. I anticipated several plot points throughout my reading, and that was a bit annoying. Still, plenty of fun.
