A great thrill ride and a "future History" many of whose predictions have already come to pass. So, you ask, if the story is so good,why only three stars? Simple, parts of the Kindle version are unreadable! half a word missing here, half a line missing there. In parts the Kindle book is more like a comprehension (cloze)exercise than a novel and the parts referring to the financial markets have most of the figures missing! In short, the publisher made a really sloppy job of converting a great novel into an ebook. It is to be hoped that they've made a better job of their other Kindle offerings.
