I take it the audio is not done by James Marsters then? (I've always thought of him as inappropriatly British) Anyway I'm glad to hear it's done well. I wasn't a fan of audiobooks until my dad had a "minor" stroke and reading became difficult for him. The process and the art of doing it well is really fascinating stuff.
As a world champion bad speller myself, I was a bit thrown by the title, The Aeronaut's Windlass.
Looking up root words and suffix's helps me a bunch. Aero (denoting air or atmosphere) as in aerospace and Naut (meaning traveler or voyager) as in astronaut. Suddenly The Aeronaut's Windlass is quite lovely. Espacially considering my initial reaction to learning the new books title was, "The huh now".
