After volume 1 that started on a flying, where the action takes place on a Space Opera bottom and post-apocalyptic universe perfectly "SF" for my taste ... one falls here (I speak of Volumes 2 and 3 ... I have not had the courage to read 4). Apart from two or three of the characters in "The Ender strategy" that can be found (in a very different context), the novel has on the name. What a disappointment! The text is difficult to read; we find endless metaphysical descriptions, history and the floundering serves only as a medium for philosophical-humanist discourse irrelevant and extension. We can not wait it to end, but it goes on and on. In short: a mystical and spiritual boiled to avoid: keep up in so-tome 1 to keep a good memory of Ender.
