Grace Ann Terhune is beside herself because her mother's salon may close because of a mistake. Violetta has been the proud owner of Violetta's Beauty Shop for decades, but suddenly all of their clients have been going to the new salon in town -- Snippets. Grace Ann can't help but feel guilty about this since this all began with her. She pushed her mom to hire Social Media Consultant Lisa Butterworth, who used their client list to send out emails for a few months and then suddenly left. But it ended up that Lisa actually worked for Snippets; suddenly, the Violetta clients began getting personalised deals that just undercut Violetta's prices. Suddenly, Violetta's goes from a busy, thriving beauty shop to a deserted shop with Violetta telling her workers to take days off.

As if things didn't look dire enough, an inspection turns up a mold issue which will close the shop for at least several weeks, pending the cooperation of the insurance company. And Violetta gets word that the local historical society has been notified that her shop may qualify to be listed as a historic site, which would mean that all of the renovations she did to turn the place into a salon and house would have to be undone so that house would look the way it originally did. Just as things couldn't look any worse for the Terhune family, Lisa Butterworth is killed on Snippet's property, on the same night that Grace Ann decides to go there to see what their salon looks like, making her a top suspect.

As luck would have it, her ex-husband, a police officer on the St. Elizabeth police department is of the first on the scene, and he is all too eager to solve the case, even if that means arresting Grace Ann. This motivates her to solve the case herself, but it turns out that Lisa has pulled her "stealing a client list" act on several other businesses, as well. Not only that, but she was the manager of Snippet's, and she didn't treat her employees very well, giving several people motives to kill her, including the finance person who suspected her of stealing money and a staff member who was next in line for the managerial job.

WAVE GOOD-BYE is so nicely written that I couldn't read it quickly enough. I loved the tension in the book, as I couldn't wait to find out what would happen to Violetta's, as well as to all of the people who worked there. I also loved how tenacious Grace Ann was in wanting to solve the mystery both to prove herself innocent, but also to help out her colleagues and her mother. The romantic interests in this book were a great addition, and I am really eager to see the progression of this in the next book in the series (and I DO hope this series is continuing!). The Southern Beauty Shop Mysteries is not to be missed!
