In his lengthy introduction, Pynchon himself pans most of the stories in this collection. Of the five, only "Entropy" and "The Secret Integration" were truly enjoyable, and in my opinion, the latter is quite a gem and worth the book's price on its own. "The Secret Integration" is both heart-warming and -breaking, and it's place is near the top of the list of short stories I've read. Now that I have read all of Pynchon's easily attainable work prior to Mason and Dixon, I'm ready to dive into his latest.
