Nell is determined to find her beloved missing au pair in this vibrant adventure set in, and underneath, Paris. Penelope Magnificent spends as little time as possible with her awful parents--a grocery-mogul father and a fashion-obsessed mother who loves expensive purses more than she does her daughter. But when they mention an important trip to Paris, Nell begs to come along. Paris holds something very dear to her: her old au pair Perrine--Pear--who lives there. Pear used to write to Nell every week, promising to come to her rescue, but recently the letters stopped.
