I was given a strong recommendation for this book.  I was warned about an epic twist, and that even though the protagonist was a YA, it wasn't a YA book.I have to say I wasn't massively impressed.  The plot twist (assuming I have the right one, I'm trying to avoid spoilers) was predictable, I called it before the epic encounter.  I felt the plot lines with Ender's siblings was for the most part useless (maybe it has some importance in sequels).  I really felt it was written to make the reader feel sorry for the put upon kids, which I explained to the person who recommended the book to me I was not interested in reading.  And it would be nice to have at least an explanation of the device that could communicate over light-years, the physics there was pretty weak.That being said, the story was decent. Characterization was good if predictable.  I liked how the author essentially predicted tablets (the tables the kids used), and the influence of anonymous writers on the Internet.Overall, a decent sci-fi read.  I don't see it as awesome as the public perception seems to be.
