If you love good science fiction, particularly that which is related to the world of robots, you will be filled! In this collection of short stories, you can discover the evolution of robots in different situations that always have problems to solve. You will have the leisure to appreciate with what logical sequences heroes are drawn from situations that at first glance parraissent unsolvable. Here again the genius of Asimov is highlighted ... Personally, I read this book 2 times and I think I would have no objections to read it a third time!
