A novel parallel to the Shadow Strategy except that the story is told through the eyes of Ender. It is a SF novel, futuristic, and I would also psychological, that is to say, we know the thoughts and feelings of each character throughout the book. The author has put suspense all along history, and it gives us to reflect on some points, and this book deserves this reflection. However, the fact that children under 15 years behave like marine, is little consistent and hardly conceivable, but reading is not less pleasant. This is a book that I recommend to teenagers and adults, that deserves reflection and the end is surprising.
