This is the first and last books of Bogdanov brothers I read. Arriving at 2/3 I want to rest the final. Their story is hollow. They give credit based here and there of famous physicists. I have the impression of seeing a TV show about the paranormal where one makes us sparkle sensationalism without bringing us more, only that the mystery remains and we have not the slightest idea what s 'is happening. It's pathetic!
