The Eternity Cure (Blood of Eden #2) by Julie Kagawa

Allison Sekemoto has vowed to rescue her creator, Kanin, who is being held hostage and tortured by the psychotic vampire Sarren. The call of blood leads her back to the beginning—New Covington and the Fringe, and a vampire prince who wants her dead yet may become her wary ally.

Even as Allie faces shocking revelations and heartbreak like she’s never known, a new strain of the Red Lung virus that decimated humanity is rising to threaten human and vampire alike.
