One for Ahl 

When refugees from the war-torn country of Ahl face extreme discrimination, Jane is nominated to represent her people in Listuan’s hero program, which trains a handful of idolized saviors for each generation. However, instead of bringing peace to the refugees, Jane is possessed by a demon of forgotten origins and targeted by a powerful abuser. Pulled into conflicts both ancient and young, Jane must fight for control and search for her purpose, all without understanding her past. One for Ahl is the first book of "The Ahlian Chronicles".
