Game Changer | A KOLTC Fanfic

What if Sofie Foster's team had another member? Someone with not one, but two, a new, unknown abilities, who was a Counciller's adopted daugher, might I add? That would be a true game change, I'd say.
Just a heads up, this is my first story, so expect some grammar mistakes, plot holes, etc. Thanks for reading my story! (:
I do not own any of the characters except Rose, Starr, and Bianca. All credit for other characters goes to Shannon Messanger, the publisher of KOTLC.
