There lived a girl named Petra Peña, who wanted nothing more than to be a storyteller, like her abuelita.
But Petra's world is ending. Earth will soon be destroyed by a comet, and only a few hundred scientists and their children - among them Petra and her family - have been chosen to journey to a new planet. They are the ones who must carry on the human race.
Hundreds of years later, Petra wakes to this new planet - and the discovery that she is the only person who remembers Earth.
