Jaclyn the Ripper

In "Time After Time", H. G. Wells didn't just write The Time Machine; he actually invented and built two of them. Jack the Ripper stole one and travelled in it from 1893 London to 1979 San Francisco. By the time Wells could follow the Ripper to the future, the killer had left a bloody trail of murders. When Wells arrives, he falls in love with young Amy Catherine Robbins...who thus becomes the Ripper's next target. With Amy's help, Wells sends Jack to the end of time. Wells returns to his own time with Amy, who leaves her world behind, determined to live happily ever after. But as happens in Wells' own novels, things don't always work out as they should. Amy misses her family, and without telling Wells, travels from 1906 London to 2009 Los Angeles to visit them. In a tragic accident, her time travel frees Jack the Ripper from his prison in the far future. Jack's DNA mixes with some of Amy's, and Jack is transformed into a woman. Now Jaclyn the Ripper sets out on a new killing spree, vowing revenge on Wells and Amy. Wells follows Amy to modern LA, but neither he nor Amy know Jaclyn is on their trail.
In the brave new world of the new millennium, Wells must navigate the confounding ways of cell phones, the Internet, and identity theft and find his wayward wife...before the Ripper can slay her.
