I always enjoy time travel novels and this one was better than most. Of course, this was made into a movie shortly after it was written in 1979 and it remains one of my favorite films from that time period. The movie pretty much follows the book where H.G. Wells must follow Jack the Ripper to 1979 San Francisco to try to prevent him from continuing his evil crime spree. However, when Wells makes it to 1979, he falls in love with Amy Robbins and must protect her from the diabolical ripper. And 1979 is far from the perceived Utopia that Wells predicted for the future. Overall, very enjoyable. I would recommend both the movie and the book. Alexander also wrote a sequel to this, Jaclyn the Ripper which I also have and plan to read next. Looking forward to it!
