The breathtaking sequel to the #1 New York Times bestseller, Immortal Dark! Like all ruinous things, he came from the abyss. Kidan Adane has finally embraced her darkness. She's killed without remorse, lied, and broken Uxlay University's most sacred law by inviting elusive rogue vampires, the Nefrasi, into Uxlay. Trapped with a violently unstable vampire, and reeling from her sister's return, Kidan wields her anger like a weapon. She vows to master her house and protect the sacred artifact hidden inside, even if it means forging an alliance with the depraved leader of the Nefrasi, Samson Sagad--and betraying Susenyos. A dangerous new philosophical text seems to hold the answers and promises the very thing Kidan has lost: control. Even as the dark pages consume her, Kidan knows no soul at Uxlay is trustworthy--least of all Susenyos. For Kidan and Susenyos, the lines of loathing and attraction may blur, but the quest for power rules them both. And neither is willing to surrender. As devastating secrets resurface from the past, Kidan and her sister, June, must finally confront each other and take their rightful places in the looming war.
