The Tournament Of The Unchosen

Raine was born a second child. "Second-borns" are sent away from their families, used as entertainment for the citizens. They are given two chances at living:
The first: being so beautiful and strong-willed (or whatever an important societal suitor is looking for in a woman) that they are Chosen.
The second: Surviving the Tournament of the Unchosen.
If they are unable to be Chosen, most bet their odds as dead. The tournament was instituted by the Administrator, as a way to kill off unwanted girls that are deemed as unworthy and unacceptable.
Surviving 17 other girls, who are all fighting for their lives, seems almost impossible to Raine.
That is, until she finds out her own secret. A secret that the Administrator did not want her to know. A secret that changes all she thought she knew about the world she lives in.
She must fight to be the last one standing and have a chance at a normal life-or, unknowingly, the life the Administrator has planned-and with her secret, she thinks she can win.
