I’m interested in writing an essay for the Letters about Literature writing contest, sponsored by the Library of Congress. http://www.read.gov/letters/

Which of the following two books should I use?
Brave New World by Aldous Huxley (written in early 1930s)
Fahrenheit 451 by Ray Bradbury (written in early 1950s)

I already read both books over the summer.
