“Immortal Darkness” is a story about our base desires, about the eternal drive for power, and about how dangerous people can be—especially when their actions are driven by love. In ancient times, vampires bound themselves with the Three Prohibitions that limit their power, and made peace with representatives of humankind. Years later, in the heart of that union between vampires and humans, Uxlei was born: a closed-from-the-world university where the mortal and immortal learn to coexist. Kidan, from the ancient Adane bloodline, spent her whole life trying to escape her inheritance. But when her sister is kidnapped in the middle of the night, Kidan understands: all roads lead to the place she feared most—the Uxlei University. To find out what happened to her sister, Kidan will have to master the ancient philosophy that bridges the world of mortals and immortals, plunge into the intrigues that have shaped vampire-human society for years, and face head-on a cruel vampire from her House—the very one, Kidan is sure, who kidnapped her sister.
