Although other reviewers have rated this book execellent, I found it very hard going. The book is classed as a thriller, but is more akin to a Science Fiction Book (although I'm sure other's would disagree), and from the start I admit I am no real fan of science fiction.
Yes, the research was excellent, and certainly you completely beleive everything the author says could happen in regard to Mother Nature, although his work on nuclear Silos and the release of nuclear weapons seems to date from early Cold War practice,and does not represent the current system in place. Yes, if you want to read a book on how the world could end via Mother Nature herself, this is the book for you.
Yet I feel that the book reads more like an academic paper than a novel. The characters have no feel to them whatsoever, and therefore seem hollow and wooden, thereby making the book appear to be more distant. Furthermore at times the author goes into far too much detail, and loses the reader.
Most books I buy and read continously, Dust was more of a chapter at a time.
