The interest of this novel lies in the description of the worlds and cultures, to say the least original, that appear in it. As for the planets of this solar system, I think especially this strange endemic plant that conquered the whole of its environment, and it is other people who have adapted to it. For "morals" of human beings, that allowing the murder under certain conditions particular comes to mind. As for the story itself, namely seeking a terrifying weapon, it has unfortunately little fantasy if not the fact that there is no real happy ending. To read all the same whether you are "fans" of the author, otherwise admirable. Good reading
