Samuel R. Delany: Babel-17

I reread this recently, because I want science-fiction and I remembered that I'd read this and liked it but that I was more than a little fuzzy on the plot. We own a copy, this edition which is beyond fugly by the way - I'd much rather own the one pictured on the Wikipedia entry (the first edition paperback cover), at least that one is retro fugly. But but but, it's the contents that matter, the contents above all, and isn't this a good novel to use to discuss just that.
