Query: Worthy of Ender's Game

I have read all of the Ender's quartet, and I feel that Ender's Shadow is worthy of its "parallel novel", Ender's Game. In Ender's Game, Bean is mentioned, but you really dont know how valuable he was to Ender until you read Ender's Shadow. I think in Ender's Shadow, Card really gets into the mind set of a child Bean's age. You might think it immature, but if you really think about it, its just what a child that age would think. I personally believe that it is equal to Ender's Game, they both have great storylines that can only be compared with their equally great viewpoints.
