Kelly Mullen writes the novel This Is Not a Game which is set on Mackinac Island, Michigan. Widow Mimi lives on idyllic Mackinac Island where cars are not allowed and a Gibson with three onions at the witching hour is compulsory. Her granddaughter, Addie, is getting over the heartbreak of her fiancé, Brian, dumping her and cutting her out of the deal for the brilliantly successful video game, Murderscape, they invented together (with Addie doing most of the heavy lifting).
When Mimi gets an invitation from local socialite Jane Ireland--a seventy something narcissist who is having an affair with her son-in-law--to a charity auction, it is the perfect excuse to get Addie to join her for the weekend. What Mimi isn’t telling Addie is that a blackmail threat from Jane looms over the party’s invitation.
