The Lathe of Heaven is about George Orr, an addict dependent on drugs that suppress dreams because his dreams could change reality. It's short, just below 200 pages but very thought-provoking. I like how in this book, it stays focused on one city, Portland, Oregon, despite the fact that George's dreams changes a lot about how the world works. It helps the book stay grounded and focused. All throughout, we see how the book talks about hubris. George doesn't want to change reality through his dreams. He talks about how he has no right to do so, reality is the way it is for a reason. Meanwhile, his ambitious doctor, Dr. Haber uses him to change reality. He thinks he can eliminate most of what plagues humanity through George. I think that the unintended consequences shows that not only do you have to be careful what you wish for, but you also have to think about the hubris of thinking that you alone know what's best for everybody and can make these changes. The prose is also excellent, simple and not overwrought, but also not dry and boring to read. 

Overall, I think it's a good book and it also explores concepts relating to things that we're facing today like epidemics, war, and climate change. As far as classic sci-fi goes, I think that I'll definitely be reading more books by Ursula K. Le Guin.
