Doctor Who

"Ever wish you could live your last week all over again? Well, my name's Frank B. Parker, and I do it all the time. I work for a secret government project experimenting in time travel. When things really get screwed up, I'm the guinea pig they send back to take care of it. The catch is, I can only go back 7 days."

The Invaders, alien beings from a dying planet. Their destination: the Earth. Their purpose: to make it their world. David Vincent has seen them, for him it began one lost night on a lonely country road, looking for a shortcut that he never found. It began with a closed deserted diner, and a man too long without sleep to continue his journey. It began with the landing of a craft from another galaxy. Now, David Vincent knows that the Invaders are here, that they have taken human form. Somehow he must convince a disbelieving world that the nightmare has already begun.

A year after the events that took place during the "Final Battle" and equipped with an all-new completed Omnitrix, 16-year-old Ben Tennyson has to face new enemies.

Theorizing that one could time travel within his own lifetime, Dr. Sam Beckett stepped into the Quantum Leap accelerator and vanished... He woke to find himself trapped in the past, facing mirror images that were not his own and driven by an unknown force to change history for the better. His only guide on this journey is Al, an observer from his own time, who appears in the form of a hologram that only Sam can see and hear. And so Dr. Beckett finds himself leaping from life to life, striving to put right what once went wrong and hoping each time that his next leap will be the leap home.
