speaker of the dead

The Speaker of the Dead is Ender's pen name for the book he writes about the Buggers. In Ch. 15, the bugger queen communicates with Ender explaining the conflict from the Bugger point of view. Ender learns the history of the Buggers and their motivations for attacking. Ender writes this into a book and signs it "Speaker of the Dead". The book goes on to be something of a Bible among people who embrace its teachings.
