It's in her nature.

As the manager of a domestic abuse shelter, Loréal Ingram is making half the salary she's used to, behind on her mortgage, and has lost faith in being an advocate for victims after three die on her watch. When a job offer lands in her lap, she wants to take it...until a curse changes her into a humanoid spider. She's forced to share her mind and body with an insect spirit who thrives on death.

The arachnid, her Mr. Hyde-like personality, is fueled by vengeance, and the handler who should be managing her kills sucks at his job. One abuser after another dies and the trail leads to Loréal. She learns that the handler has botched the curse and unleashed The Spider Inside Her upon wrongdoers. If she doesn't find a way to lift the curse soon, the arachnid will take complete control of her body and kill anyone who crosses her path, including the one person who might be able to save her.
