Eighteen year old Kayla Morgan wakes up one morning, to find that no one is who they say they are. Her parents and younger brother are just too chipper to be real. And then they attack her. Her suspicious are confirmed.
Kayla is on the run.
That is when she is picked up by an elite group of people that know exactly what is going on. But what is going on is exactly what they won't tell Kayla. Why do they need her? What is so special about her? And why is she being kept in the dark?
