Debris

Why? Why does it have to be me? Why now?

The questions of fifteen-year-old Becca Iris has asked herself ever since the 'new humans' came to Earth. Destroyed it. Took everyone that was smart ... "Geniuses," and took them to their home planet: Karthelynis.
Memories faded and a new world and life began for those Earth people. Becca soon remembers nothing of the past but of a fake identity.

She doesn't know her real name or real life, only the fake identity the Karthelyn's gave them.

This sci fi book fills anyone's mind with the "What if." The why as to the where the story will lead you.
