The last Hebrith

Holly's 17th birthday is in one week, everyone aged 17 and up are sent to the military for 5 years unless they die. She isn't ready for it considering she may lose her own life. The day that she turns 17 is the day she has to go to her hearing. Crowds gather while President Lopez calls out a bunch of names those that are called have to stand next to the President until the end where they congratulate them. The worst part about fighting in the military is that you are not fighting humans you are hunting and killing monsters. During Holly's first mission she meets an otherworldly boy that looks to be the same age as her, he goes by the name Ieberus. What will happen between them? Will she see the inner good in the monsters? Or see them as hateful creatures?
