The Tale of the Unknown Island

I went into it knowing it had been recommended but without remember anything about it or the premise. I enjoyed this story. It was an interesting style, but I didn't mind it, even liked it. I enjoyed it's brevity (I'm tired of books, particularly those meant to teach, that are longer than necessary). I feel like I need to read it again to gain a better appreciation for it.
I feel like 3/5 starts looks bad. But following the guidelines 3=I liked it, and that's exactly how I feel about this story. Nothing more (yet), nothing less.
