Cached US Kindle giveaway: 10 copies of @davidbrin's EARTH: A NOVEL, which I *have* and *have read* and *did like*. I might be in a minority there, but it is just chock-full of BIG IDEAS and characters. I'm still waiting for some of the stuff it predicted to come about (telepathic computers!). The actual end of the book caused me to not quite get the ending in Scalzi's REDSHIRTS.
This has a super-optimistic ending that we won't be getting in reality. Alas.
