Monstress

"Maika Halfwolf has begun to unlock the mysteries of her past--but the challenges of the present are only growing. Maika's journey takes her to the neutral city of Pontus, where she hopes to find temporary refuge from her pursuers. Unfortunately, Pontus may not be as safe as Maika and her allies had hoped. As the impending war between humans and Arcanics creeps ever closer, and powerful players fight for the chance to control her future, Maika finds she must work with Zinn, the Monstrum that lives inside her, in order to ensure their mutual survival. But even that alliance might not be enough to prepare Maika for the horrors to come."--Publisher description.
