On the Wings of Murder — Patti Benning

Eleanora Pacelli and her grandmother embark on a last-minute summer trip to Florida after a particularly stressful week at home in Kittiport. They are both looking forward to a nice, relaxing week in the sun, but things go downhill fast when the elderly Ann Pacelli vanishes from the hotel without a trace. In the search for her missing grandmother, Ellie makes new friends and stumbles upon a new business opportunity that might change Papa Pacelli's Pizzeria forever. With a deadline inching ever closer, she has to rely on the kindness and help of complete strangers to have any hope of finding Nonna before it's too late.
