Book: Babel-17 by Samuel R. Delany
This is one of the “SF Masterworks” that I picked up based solely on being in the collection. Most of the ones I’ve read there have been worth reading.
This is an interesting concept, and reminded a bit of Ted Chaing’s “Story of Your Life”. There were parts of the book that to be honest had me a bit confused, but overall it was an interesting classic SF story.
