Ender's Game (Ender Wiggin Series #1)

Ender's Game (Ender Wiggin Series #1) - Starts off really nice. Just started reading last night, though. Have to see how it evolves in terms of character development and so on. ...Overall I'd say that I liked this book. I'm still struggling with the end, with the concept of the three Wiggin children apparently being Earth's biggest genuises. Why would the "Speaker of the dead" idea form a new religion? I continuously return to this question. I don't outright reject the notion, and it really is just a minor issue, but one that I cannot quite grasp.
