Shattered

Samantha Pines, a senior at Westmore High School, is on her way to a New Year's Eve party when she gets into a major car accident. But instead of dying, she goes through a portal into Earth 2.0, a world of the past. She then meets Drake, who tells her the only way to get back to her world is to find the "her" in Earth 2.0 and stop the car accident from happening. But what if stopping the car accident from happening alters the rest of the world so much, millions of people die? What if stopping her from dying kills everyone else? Is she really worth it?
