My DM's been raving about Dial H, but I haven't checked it out yet.

I liked Railsea, but not anywhere near as much as I liked Embassytown. I just wanted Railsea to be much more ambitious than it was. It was a setting that called for bigness more than it delivered bigness. (You know my feelings about macrofiction.)

I will say that Mieville had a fantastic answer to the question "What's beyond the railsea?"
