It was the first book that I can recall reading that was quite definitely Science Fiction. The scale at which he imagined things was amazing. Re-reading it recently, I was struck that my nostalgia seemed stronger than the experience itself, but it pretty much got me to read every damn bit of science fiction I could from then on. So, not sure whether it's an amazing book (it was to me when I was 12), but it definitely set in motion a life-long love of science fiction books.
