Toni Diamond wins a cruise. Will the real prize be murder?

Toni Diamond, makeup artist to middle America, boards a cruise ship planning to enjoy seven days of sun, sea and relaxation. She's taking her rebellious almost-seventeen year old daughter Tiffany and her Dolly Parton-crazed mother, Linda, along for the treat. Unfortunately, the cruise isn't all bliss. Between mysterious disappearances, an outbreak of Norovirus and her sense of impending doom, Toni's barely got a moment to relax in one of the striped lounge chairs. But is there really something sinister going on or is Toni imagining things?
