Immortal Dark by Tigest Girma

Hidden in our world, a society of vampires originating in Africa, can only feed from select human bloodlines. Each bloodline represents a House more cutthroat than the next. To ensure peaceful co-existence and inherit their legacy, human children of these families must study at an elite university before choosing a vampire companion.

Lost Heiress, Kidan Adane grew up far from Uxlay University. She is obsessively protective, mildly nihilistic, and willing to do anything to save her loved ones. When her sister, June, disappears, Kidan is convinced a vampire stole her - the alluring yet dangerous Susenyos Sagad, the same vampire bound to her own House.

To stay in Uxlay, Kidan must study an arcane philosophy, work with four enigmatic students, and survive living with Susenyos - even as he does everything to drive her away. It doesn't matter that Susenyos' violence speaks to her own and tempts Kidan to surrender to a life of darkness. She must find her sister and kill him at all costs.

When a murder mirroring June's disappearance shakes Uxlay, Kidan sinks further into the ruthless underworld of vampires, risking her very soul. Here, she discovers a centuries-old threat. And June could be at the very centre of it.
