Before "Foundation" i'd read somes short-storys from Asimov, so i become insterested in his style. And what can i say now about this book? Really is a excelent piece of scifiction: Asimov united 4 independent stories in a book with lifely descriptions, a strong main-story and credibles characters in incredibles situations,...the result is just epic. So, with this book we become in eyewitness on the monumental development and fall of the human civilization... becoming it in a surrounding journey trought our future and past.
Output:
Positive
