Appears to include the great majority of George Orwell's notable works. Not bad for 99 cents, the individual books usually cost about that!
Specifically
- 1984
- Animal Farm
- Coming up for Air
- Homage to Catalonia
- The Road to Wigan Pier
- Keep the Aspidistra Flying
- A Clergyman's Daughter
- Burmese Days
- Down and Out in Paris and London
- Collected Essays
Note that all these titles are in the public domain so available for free at sites such as http://gutenberg.net.au/plusfifty-n-z.html#orwell
One advantage to paying would be possibly better format for reading, but personally I would just read it in my browser using html. If you're really keen I can find a link for grabbing a free pdf or epub.
