Whistling in the DarkBy: Lesley Kagen Funny, wise and uplifting, Whistling in the Dark is the story of two tough and endearing little girls and of a time not so long ago, when life was not as innocent as it appeared. It was the summer on Vliet Street when we all started locking our doors Sally O'Malley made a promise to her daddy before he died. She swore she'd look after her sister, Troo. Keep her safe. But like her Granny always said actions speak louder than words.
