Arrows

A dystopian world where society is broken up into three Tribuses Gunmen, Archers, and Forged.
Each year all kids in the 10th grade take a test to fine out what Tribuses they're in. And are to survive a month in the arena where anything is legal even killing.
But for Noah Hallows this test means so much more. Her parents have raised her to kill since birth. Her family are all in Gunmen the richest Tribuse that has control of the government. But her family all being Gunmen wasn't out of luck. They killed to keep it that way.
Noah is faced with the chance of killing or being killed by her older brother Hunter. And Noah is stuck between freedom from her family and being safe.
