Expecting to read more of the "same-old" doomsday speculation rampant on Art Bell's radio show, this book suprised me with both its message and its scope. With the exception of some of the initial chapters, which provide an overview of recent theories regarding the age of mankind, the entire book was new material for me. It was the first time I'd heard of a "superstorm", how one would form, and the effects such a storm would have. The prospect is terrifying.
The book is so well-written, however, that I felt the book's message was a call to action rather than an simply a disruptive alarm. The authors cleverly intersperse realistic-yet-fictional scenes of the onset of such a storm between the factual, sometimes dry prose. The result is a book that is extremely informative and a pleasure to read (similar to "The Hot Zone").
Grounded in science and only minimally speculative(the authors state very clearly where they do so), this book is well worth reading and contemplating. I hope the book finds its way into academia soon.
