Infernal Vow (Immortal Dark, 3)

Kidan Adane teeters on the brink of a collapsing world—where old rules no longer hold, a forbidden power is stirring, and the consequences of past decisions are beginning to take their toll. Determined to restore order to her life, Kidan seeks the ultimate power: becoming a Sage. To save Yusef, restore GK’s humanity, and forge new bonds, she must travel to Ethiopia to train under an ancient vampire. Now that love has turned to hate and humanity hangs by a thread, Kidan must decide how much she is willing to sacrifice to save the very world she has already condemned.
