The first part follows Ender in a four book quartet:
Then the second set follows another character from the first book (Ender's Game) named Bean:
Shadow of the Hegemon and have started Shadow Puppets. I don't have Shadow of the Giant yet but I will obtain it soon enough. There are other books within the same universe that are soon to come out which I will greedily snatch up. But until that point and when I've finished what has been published I will begin reading the Dragonriders of Pern series by Anne McCaffrey, or at least Dragonflight, Dragonquest and The White Dragon. After that is finisehd I will start the Twilight series. I don't know where I'm gonna go after that though.
