I have recently finished reading Ender’s Game and Speaker for the Dead, and have just started Xenocide.  They are amazing.  I do not usually enjoy fiction, but I can not put these books down.  It is my understanding that the first two books are the best, but I think I will probably read the whole series regardless.  Orson Scott Card will definitely be near the top of my Top Ten Favorite Authors list when I do one.  After the Ender Saga, it is on to The Memory of Earth.

Wow!  And I just found this!
