Brave New World ($2.99 Kindle), by Aldous Huxley, also has a deal on the companion audiobook for $4.95 (but is $8-$10 in other stores I checked). This is a "classic" that everyone should read (if only to be able to understand some of Apple's old SuperBowl ads).
Today marks the 120th birthday of Aldous Huxley. The Brave New World author’s scathing critique of the mass media and the government (and their use of technology) positioned him at the center of intellectual discourse and made him one of the most widely read science fiction authors of his time. Enjoy this collection of Huxley book cover art worthy of his surreal stories. http://flavorwire.com/469465/20-mind-bending-aldous-huxley-book-covers/view-all
