Sparrow is a man of many secrets. Infected with lycanism by a werewolf’s failed spell, he now works for the Van Helsings as their talented and ruthless torturer. Sparrow imprisons Meguitte—Talen's witch-turned-vampire child—while she is enthralled by their unfortunate mate bond, and convinces her to gift him with a magical cuff capable of controlling the self-defined ‘abomination’ inside him. Unbeknownst to her, the cuff will serve as a weapon against any supernatural being that threatens the Van Helsings’ agenda.

While Cameron and Rhett work to save the members of the pack imprisoned in the Havermouth High School gym, Sparrow captures Heath, torturing him to the point of death. Talen and Sigrid, with the help of Aislen and a powerful gathering of witches, manage to rescue Heath from Sparrow’s grasp…but not soon enough.

Saving Heath’s life, however, is another matter, and Talen is forced to make a decision that will affect all of his mates and their entire future.

With Havermouth in the grips of a waterborne illness and face-eating zombies wandering the streets, can Aislen and her mates save their bonds, Havermouth—and the world—from the terrible end the Van Helsings have planned?
