Olivia is riding high after her Sweet Four O'Clock summer tour. Michael is hard at work building their dream home and her sister, Sage, is expecting.

Yet things take a dark turn when Olivia follows Mayor Maguire's barks and stumbles onto the body of Beats's Malone. Someone killed the talented drummer and dumped his body in a public parking lot. Olivia is on the case once more! Not only is she determined to uncover who is behind Beat's death, but to discover how it connects to her pregnant sister.

Secrets abound with everyone—including Mayor Maguire—acting odd. But when an anonymous source sends the police a video of a skateboarder riding through downtown Lily Rock in the dark Olivia begins to wonder if this is a clue... or a threat.

When Sage ends up in the hospital, Olivia is ordered by the handsome new Lily Rock doctor to drop everything and care for her sister at home. Janis Jets must continue the investigation on her own.

Can Janis track down the killer without Olivia's help? Or will Olivia have to choose between family obligations and stopping a murderer from striking again?
