Orson Scott Card's
Speaker for the Dead
I finially got in to this book today after I'd had it for a few weeks. I picked it out while I was down the shore some weeks ago after I had promptly finished Ender's Game in two days. I happened to stumble upon Catch-22 in the same afternoon and I ended up reading that before Speaker. Catch-22 was really good except when I didn't read it enough. You see, I began to read it when I had a lot of time at the shore. As soon as I was home, Natalie was also and so I spent a great deal of my time with her. The next week I picked it up every once in a while but not a whole lot and I finially began reading it a lot when I got to college. I just finished it last night so today I started a new book.
I like it so far, I really enjoy reading Orson's intros because they shed so much light on the process by which he crafts his books, especially this one, and, I beleive, they add to the story.

Pick it up. You don't necessarily have to have read Ender's Game to enjoy it.
-edit- I originally made this post to express a particular feeling about a line Orson uses. Mozilla then crashed about halfway through the post because I had neglected to update from .6 to .61 - of course I updated and then forgot my original point. Here it is;

"[to] see not beasts but brothers, not rivals but fellow pilgrims journeying to the shrine of intelligence."
