The trilogy for Ender has a more philosophical and religious feel. It deals with Ender 3000 years in the future, in another situation where xenocide may be the only answer. There are a lot of new characters, as the story couldn't support with just Ender and Valentine. This is an adult Ender but you can still relate to all the characters. Speaker for the Dead, Xenocide, Children of the Mind Ender's Shadow is what OSC calls a "parallax" - a parellel telling of the same events in Ender's Game. Bean is the primary character here, you will see a lot of how he influenced the events. It is quite good, and it flows well with the original. All the characters are there including Graff and Mazer Rackham, and some new ones. It stands on its own as a book though, so you won't be disappointed. The trilogy for Bean deals with a near-future Earth after the Buggers have been destroyed. It is more political and military. Nations are preparing for war again as they use their new genius children against each other. Minor characters from Ender's Game play a more powerful role here. You'll also see Ender's brother, Peter, becoming an important character. Shadow of the Hegemon, Shadow Puppets, Shadow of the Giant OSC is working on more books. One will be a bridge between the Bean and Ender trilogies. Another will be focused on Mazer. We'll see whenever they are done I have read some of Card's other works... his Homecoming Saga takes a more religious tone, but it still very character driven. I could connect with it. Will try reading the others when I get the time.
