Celestial Matters really should be available on Kindle, not that this is Richard Garfinkle’s fault. I can almost guarantee that the reason it’s not is because the rights haven’t reverted, and Tor Books can’t be arsed to digitalize it themselves. I mean, what’s in it for them? It’s just a hard science fiction novel where the physics are Aristotelian and the cosmology Ptolemaic. Who on Earth would want to read that?
…I’m being sarcastic. And quietly grateful that, for better or worse, I’m unlikely to ever have this particular problem.
