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 arcane society she was born into, where human bloodlines gain power through vampire companionship. When her sister, June, disappears, Kidan is convinced a vampire stole her—the very vampire bound to their family, the cruel yet captivating Susenyos Sagad. To find June, Kidan must infiltrate the elite Uxlay University—where students study to ensure peaceful coexistence between humans and vampires and inherit their family legacies. Kidan must survive living with Susenyos—even as he does everything he can 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.
