Ender's Game was my favorite book when I was 12, so I read a whole hell of a lot of Card's books before I knew anything about his personal beliefs. I tried so hard to think they were awesome, but everything after Ender's Game is pretty uninspired.
1. Character glimpses a new way of life. 2. Character is misunderstood and persecuted by society. 3. Character collects followers and heads off into the middle of the wilderness to found a new society.
This is an effective summary of not only the Ender's Game series but his Homecoming saga, Alvin Maker series, Lovelock, Wyrms, Treason, and probably a few others.
