Jack Jacobs and the Doomsday Time Machine

In this futuristic time travel puzzler, Jack Jacobs and his organic supercomputer, Jennifer, have been gone from Earth for sixteen years. When they finally arrived back, they expected it to be in the year 2199, but found it was one-hundred years into their past. An analysis of their last time tunnel revealed there was a time distortion that not only shifted them into a new universe, but was related to an event from another galaxy. Their spaceships carbon based nanotube computer also registered Jacobs as the one who discovered the galaxy, yet he had no recollections. In their quest to come up with answers, they determine their spaceships quantum gravity drive is caught up in a series of time distortions, and the only possible solution to their predicament lies in a distant galaxy they may have visited, but have no way of knowing. They must now trek across the universe to a mysterious galaxy millions of light years away. What they found there was something neither of them ever expected. It took them where no one has ever been before.
