Accidentally not Amity

Maritza had lived a mediocre Candor life and was prepared to go to the Amity faction for a great and peaceful life. That however did not happen when she accidentally choose Dauntless. With nothing left to live for she could easily become the greatest dauntless ever. But this year initiation has changed and a young cold hearted leader and his arch enemy are training the initiates, what will happen when Maritza attracts a little too much attention to herself?
I do not own these characters except for Maritza, they belong to the wonderful Veronica Roth so does some of plot line.
