As most of the other reviews have noted, James P. Hogan here presents a somewhat unevenly written story. However, that being said, there is a class of reader (such as I) that really appreciates clever sf and surprising plot twists.Multiplex Man does have its moments of annoying polemics so frequent in Hogan's work. However, the incredible entertainment of this book easily makes reading it well worth while. Towards the end I couldn't put it down; the adventure was so exciting, the explanations so satisfying.If you have difficulty finding this out-of-print book, a little Web searching can reward you with this gem.
