I'm Here and I Am Alive

Selma Kine, the last of kind. She was sent to Earth on the day she was born. She was taken in by a lovely couple. She never truly fit in during high school. On her 21st birthday was when she found out where her foster parents found her.
When she founds out who she is, war is coming to Earth. Now she must defend Earth and learn more about herself.
*Futuristic kind of story.*
