Jack Jacobs And the Doomsday Time Machine

When Jack Jacobs arrived back to Earth after sixteen years, he expected it to be the year 2199, but found it was one hundred years into his past. He wonders if it is a malfunction of his spaceship's quantum gravity propulsion system, but also finds it is related to an event inside another galaxy. He must now trek toward the new galaxy for answers. What he finds there takes him where no one has ever been before.
