Do we still get an email from the CCA and forward that to the dispensary, or do we have to use that CCA portal? I am having trouble accessing the CCA portal and haven't received an email from the CCA. Last year, I got the email from my provider and the CCA pretty much at the same time.
I recently read Alastair Reynolds' House of Suns and Karl Schroeder's Lockstep. These books are both set in interstellar civilizations that lack faster than light travel and communications; despite the godlike powers the characters are granted by their advanced technology, they are bound by the merciless reality of relativity and time dilation. Reynolds Revelation Space Series is another example, Ursula K. LeGuin's Ekumene almost meets the criteria, but the ansible allows Mobiles to instantly communicate with the Stabiles on Hain from anywhere in the galaxy, and Rocannon's World shows an instantaneous drone strike during the League of Worlds era.
What are your favorite Sublight Interstellar Civilization books?
