Immortal Dark

The Cruel Prince meets Ninth House in this dangerously romantic dark academia fantasy, where a lost heiress must infiltrate an arcane society and live with the vampire she suspects killed her family and kidnapped her sister. 

It began long before my time, but something has always hunted our family.

Orphaned heiress Kidan Adane grew up far from the elusive society of vampires she was born into, where human bloodlines gain power through vampire companionship. 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 same vampire bound to her family bloodline, the cruel yet captivating Susenyos Sagad. 
 
To find June, Kidan must infiltrate the elite Uxlay University—where students study to inherit their family fortune and select vampire companions. 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's wickedness speaks to Kidan's own violent nature and tempts her to surrender to a life of darkness. She must find her sister and kill Susenyos 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. There she discovers a centuries-old threat. And June could be at the center of it. To save her sister, Kidan must bring Uxlay to its knees and either break free from the horrors of her own actions or embrace the dark entanglements of love—and the blood it requires.
