"Good story, okay narration"
First, this isn't Ender's Game. It's an entirely different kind of story, so if you're looking for the pseudo-military sci-fi action of Ender's Game, you will be disappointed. That said, this is one of Card's better works, with rich, interesting characters and a fascinating (if slower-moving) plot.
The multi-person reading is not very well done, however. At best, it's distracting; at worst, obnoxious--one of the female readers, in particular, has a habit of reading every sentence as though it's the saddest and most important thing ever written. The book's main narrator is (fortunately) quite good.
Overall, recommended.
