All right, the poll is closed. For a while it looked like I would end up with two or three books with the same number of votes but it appears someone cast the wining vote in the nick of time.
Babel-17 - Samuel R. Delany (27%)
Tau Zero - Poul Anderson (22%)
Dying Inside - Robert Silverberg (18%)
Cat's Cradle - Kurt Vonnegut (18%)
The City and the Stars - Arthur C. Clarke (13%)
I have just finished reading Adrian Stone's latest so that review goes first. I hope to have a review of Babel-17 for you by next weekend. I you voted for one of the other books, I will end up reading those eventually ;)
Thanks for voting!
