Everything points to suicide… Research scientist, Kennedy Walker is shocked when her mother dies and the police rule her death a suicide. Her scientist-mother was on the verge of a scientific breakthrough, and Kennedy knows her mother would never end her life, but the detective won’t listen. Kennedy worked alongside her mother at the lab, and Kennedy commits to finishing her mother’s work, but before long, it’s clear that her mother was killed to stop her from completing her project. And she must prove them wrong. Kennedy digs deeper, garnering the killer’s focus, and he puts her in his cross-hairs. She can’t give up on such an important project, so she swallows down her pride from Erik Byrd’s rejection and hires Nighthawk Security, not only to protect her, but to help find her mother’s killer. It takes only one look for both of them to know their feelings for each other haven’t gone away. With so many people counting on her to complete the formula, giving in to old feelings is a distraction neither she or Erik can afford, and they both need to keep watch. Especially in the darkest hours of the night, when the killer comes out to play.
