I finished the short novel last week and really, really enjoyed it. It is a compelling read, well-written, and very thought-provoking. It is about more than just censorship — it is about thought-control, though with a little more optimistic point of view than, say, 1984.
I put Fahrenheit 451 on my Fill in the Gaps list when I started it last year, and I'm really glad I did. It "forced" me to get around to reading something that is very much a book I wanted to read and intended to read for a long time. I'm glad that I put the list up and have been plugging away at some fun titles so far. Fahrenheit 451 is one of the best I've read from my list yet.
