Are you excited for the long-awaited SciFi classic, Ender’s Game, to be released on the big screen this November? Before seeing the movie, I plan to brush up on the story.
Don't have time to read it in its original format ? Try the graphic novel adaptation.
Ender in Exile 
Card originally wrote Speaker for the Dead the year following Ender's Game. Card later added more novels to the Ender Wiggin series and other stories branched off from the Ender Wiggin series which were also adapted to graphic novels, including Ender's Shadow  and Formic Wars , a prequel to Ender's Game.
Which one will you start off with?
