This Resort Has The Recipe For Disaster!
Nancy's thrilled that she, Bess, George, and Hannah will be attending the grand opening of the newly renovated Gourmet Getaway. Not only will they be able to eat four-star meals prepared by master chefs, they'll get to take cooking classes with them, too. But before the table's even set, problems start plaguing the resort, both in and out of the kitchen. Nancy can't believe it's just bad luck, but who's causing all the problems?
Nancy puts her cooking on the back burner so she can devote her attention to solving the mystery. Can she manage to find out who's behind the trouble before more sabotage is served?
