A Rip in Time (Out of Time #7) by Monique Martin

Another fantastic, time-travelling adventure for Simon and Elizabeth Cross. This time they are sent back to Victorian London with the sole purpose of preventing the murder of Jack the Ripper thus restoring the time-line and their lives together as they know it. But, first of all, in order to prevent his murder, they have to figure out who Jack the Ripper actually is. At least they know when and where he will be, in Whitechapel committing his own gruesome murders. At the same time, the couple must face off an old adversary who is responsible for the rip in time.

I loved the blend of historical fact and fiction. The adventures of Simon and Elizabeth never grow old. I eagerly anticipate their next adventure as well as finding out what happens next with Victor. Not to mention their other friend, Jack, whom I'm assuming was restored to the time-line from which he disappeared at the beginning of the story.

As this is book 7 and if you haven't read any of the others in the series I recommend you start with the first book for free on your kindle 'Out of Time: A Time Travel Mystery.'
