With the growing number of people sick and dying in and around Santa Cruz, the local werewolf pack sends a small group to Colorado to see if the research center can help. Caroline, coven witch and biology professor at the local college insists on being included, even though the research center is for werewolves only. She's done the research thus far and knows they'll need a witch on their team.
Mazzy loves her pack, though as an introvert, feels separate from the boisterous group. With a background in chemistry, she leads the secret research facilities lab. When a serum containing black witch magic is brought to her, she's excited about the challenge, up until it comes with a witch. They shouldn't be allowed into werewolf territory.
Can the two top scientific minds in the werewolf and witch communities work together to undo the damage of the black witches?
