Ayn Rand's Anthem is in the public domain and there are numerous editions of it in the Kindle store and available at most free book sites. What's been missing was the other novels that are classics (and required reading for high school and college English students).
Atlas Shrugged ($1.99)
The Fountainhead ($5.99)
Night of January 16th ($1.99)
Virtue Of Selfishness ($1.99)
For the New Intellectual: The Philosophy of Ayn Rand ($1.99)
