If you haven't read Wool, I'm jealous of you -- I wish I could read it again for the first time. Hugh Howley's series of self-published novelas is one of the best works of science fiction I've ever read.
Even better (or worse?): Film director brothers Ridley and Tony Scott have bought the rights to make it into a movie.
But this looks like a trailer for the upcoming book -- a collection of the first five novelas -- which Random House is publishing in 2013. Watch it, get obsessed, and then read.
