Each of those children are taken away at birth by the government and returned to their parents on their tenth birthday with no memory of what happened before. Only this ten year old girl remembers everything, including her own birth, and these people aren't her parents. She soon realizes that there is a great and terrible power within her that she doesn't know how to control. It seems this beast that humanity has been trying to keep caged away in their children has finally slipped it's leash.
