Childhood's End (1953)
Arthur C. Clarke
As a fan of all things sci-fi, this book had long been on my radar but it never got read until I heard two speakers mention it within a few days of each other; even I can get that hint.
“No utopia can ever give satisfaction to everyone, all the time. As their material conditions improve, men raise their sights and become discontented with power and possessions that once would have seemed beyond their wildest dreams. And even when the external world has granted all it can, there still remain the searchings of the mind and the longings of the heart.” --Childhood's EndI'm so glad I waited to experience this story as I have a much different take on the ending now than I would have earlier. It's just the perfect sci-fi book for the newly awakened, in my opinion, and I don't think there's much more to say about it than that.
