Alien Disruption

Sara didn't start out expecting to change the world. She inherited it from her dad and grandad, but she didn't expect it. For much of her early years, Sara thought her family was pretty weird and there seemed to be plenty of evidence to prove it. Her late grandfather, Pete Stevenson, maybe the weirdest of all, was obsessed with chasing down proof of aliens and time travel all over the world. Incidents through the years seemed to suggest that her family had, indeed, come across evidence that alien presence was real. Informed speculation regarding alien presence had now become irrefutable fact. Now, has an actual temporal alien encounter revealed that she is Earth's chosen one?
