I loved Ender's Game, and also its sequels, enders and shadow both, the only one i think OSC did not put the best of him is Shadow puppets, written quickly and uncarefully, it seems to me...
i really think Orson will not ever write things as Enders Game, Speaker for the death, Treason or Wyrms (and some other left behind) again, he is much occupied in his speeches and travelling around USA just teaching new writers than in create stories and characters as deep as he did.
Poor Alvin, his beggining was great, and... did u read the last one?? alvin has become a superman who can do everything, so you never suffer, he is too good, he is almost Jesus. The only thing that saves in that book is ArthurEstuard, the black boy Alvin is teaching the secrets of being a Maker.
I dont know, it is just i got really disapointed with the last books I read from him... >I hope the fourth shadow will be again a book, not some ideas put together and see what the quill throws off.
