It's a very good book, but not the best I've ever read. Card's other works, such as Speaker for the Dead(my personal favorite of his)and Ender's Shadow and Shadow of the Hegemon are in my opinion better or at least equal books. If you like Ender's Game because of the action, read Ender's Shadow and that series; it follows Bean, and is quite violent and action filled. If you, like me, appreciate Ender's Game more for the intrigue and philosophic elements therein, continue the series focusing on Ender.
