Very Good Condition, first edition. Review from the Booklist: In the twenty-fifth century, human society has depended for several hundred years on faster-than-light travel and an artificial intelligence called the Eschaton. Interstellar colonies are scattered all over, and one, the New Republic, has become a classic refuge for antitechnological holdouts. But the New Republic is suddenly under attack, literally, by the technology it has tried to suppress, which now appears under the name the Festival. An Earth battle fleet is on the way, but is it coming to help, to ride to power on the coattails of the Festival, or to fulfill some entirely separate agenda, possibly set by the Eschaton, which has achieved consciousness, sentience, and probably a lust for power? If no element of Stross' novel is very original, all of them are formidably well-executed, especially the meticulous and imaginative portrayal of the New Republic and its Victorian technology. In addition, the book possesses the rare virtue of neither requiring nor precluding a sequel.
