I have added two books by Jack London to the Dunyazad Library.
The Iron Heel is the earliest, and the most explicitly political, of the great 20th century dystopian novels (the others, unless you come up with a different list, would be Yevgeny Zamyatin’s
We, Aldous Huxley’s
Brave New World, George Orwell’s
Nineteen Eighty-Four and Margaret Atwood’s
The Handmaid’s Tale).
South Sea Tales is a famous collection of adventure stories – meet traders, sailors, natives, cannibals, ruthless colonist, and the occasional decent person; survive massacres, hurricanes, shipwrecks, and fire (and forgive the sometimes politically incorrect language from 100 years ago).
You can have all those adventures for free, carefully edited, in plain text, PDF, epub and mobi format.
