When Leigh’s parents’ house becomes a last-minute substitution on the regional garden club’s famous Holiday House Tour, Frances Koslow is thrilled. But the tour is tomorrow, there’s work to be done, and Frances’s dwindling and aging “Floribunda” chapter is in dire need of reinforcements. Worried about her mother’s blood pressure, particularly as sisterly tensions rise over Leigh’s Aunt Lydie’s upcoming Christmas Eve wedding, Leigh steps in to make sure the tour runs smoothly.

But perhaps Leigh isn’t the ideal choice for the task. Not when a fortune cookie has just portended the return of her infamous “bad karma.” Not when everyone knows the real reason the Floribundas have declined is because every remaining member is a whackadoodle. And not when someone’s idea of Christmas spirit is to add a little something extra to the sweet cider punch.

One dead Floribunda later, Leigh struggles to keep her family calm in the midst of swirling suspicions, flying accusations, and dubious warnings of biological warfare. But when someone threatens to silence her own all-too-curious daughter, mother-rage kicks in. Nobody is ruining her family’s Merry Christmas. Not even her family.
