Many have read Ender's Game. Some have read the Ender's series. Perhaps not as many have gotten as far as the The Ender's Shadow Series. This book is the 2nd in that quartet. I love it for the philosophical questions it poses, intriguing characters, quick paced plot, actions scenes, and the part science plays in it. Truly one to get to. Really only need to read Ender's Game, and Ender's Shadow to enjoy this book.
