A random hook-up changes her life forever. At first Levi Bonham seems like the ideal, no-strings-attached kind of guy, but Harley soon realizes that he is as dangerous as he is enticing. She finds herself plunged into a world plagued by creatures that prey on human suffering and misery. Still reeling from tragedy, Harley has to learn to adjust to her new, not-quite-human life and all that comes with it. A confusing and complicated love life. Enemies—both new and old. And above all else, she must confront her own demons to save herself and those she loves most. Her desire for revenge propels her into a centuries-old war waged in shadows. Harley must choose to put aside her vendetta and risk her own humanity if there is to be any hope for mankind.
