The only thing left is survival. Hisime Ara trained hard to be a Ranger and to overcome the hardships and abuse of her past. Her first solo mission is her chance to prove that she's not the weak girl she used to be. But when she gets lost during the mission like a rookie, that puts a dent in her confidence. Fighting the humiliation, Hisime pushes on -- but her past finds her. Abusive Narnim has a fresh torture in store for her. When he tosses Hisime in a toxic pit, only her Ranger training can save her. She must become what she's never been -- strong, because only the strong survive.
