Ten years ago, Sienna Clarke made my life a living hell, but karma has a twisted sense of humor—now she's sitting across from me in a job interview, desperate and completely unaware that the awkward girl she tormented is now her potential boss. I should turn her away, let her feel even a fraction of the humiliation she put me through, but instead I do something far more calculated: I hire her. She needs this job, and I need... well, I'm not entirely sure what I need yet, but watching the queen bee of Westbrook High answer to me feels like a good start. As Sienna struggles to navigate her new reality, I'm discovering that revenge might be more complicated than I imagined—especially when the lines between payback and something far more dangerous begin to blur. Some wounds from high school never heal, but some grudges might just ignite into something neither of us saw coming.
