Daughter of Realms - Ember East - Bog

Half-demon, half-fae Vale thought she left her violent past behind when she escaped the brutal Otherworlder training academy five years ago. Now she hides in the mortal realm, using her unique abilities to hunt demons.
But when a botched demon hunt accidentally sends her and her best friend Wren into the treacherous demon realm, Vale's forbidden gift of blood magic is exposed. News spreads like wildfire to the demon lords and now every dark creature wants her power.
Before long, Vale becomes the target of the realms - The demon lord Zephyrian unleashes ancient demons, while the fae court attempts manipulation, turning Vale's world upside down. With attacks on the rise, Vale has no choice but to master her magic or risk enslavement...or worse.
