When Milwaukee author Lesley Kagen set out to write her debut novel, "Whistling in the Dark," she never anticipated returning to the 1950s Vliet Street neighborhood of her main characters, Sally and Troo O'Malley. Still, fans wanted more from Milwaukee. What resulted was "Good Graces," which returns to the lives and adventures of the O'Malley sisters just one year after the events of "Whistling in the Dark."
