The little Ender, separated from his parents and his brother, finds himself in a space war college, where he has a crossbred ability of genius, to the chagrin of his older companions, less brilliant, that feed resentment for him . Adults watching Ender secretly develop, and do all that he does not feel happy, they are cruel and cold, one is torn psychological torture - because the book is played around the whole psychology of Ender - they inflict him as soon as he starts to feel a little good, a little out of place. The ending is unexpected, it belatedly suspect what actually happens, as the ultimate snub to Ender, who has grown up a bit, but is still too naive. A good book, saddens, grieves, revolt, and ending on a very sour note ... to read!
