Seven months ago, Edda was on the World War I front lines as one of two hundred “Hello Girls,” female switchboard operators employed by the US Army. She spent her nights memorizing secret connection codes to stay ahead of spying enemies, and her days connecting vital calls between platoons and bases and generals, all trying to survive—and win—a brutal war. Their lives were in Edda’s hands, and one day, in fateful seconds, everything went wrong. Now, Edda is back in Washington, DC, working as an American Bell Telephone operator, the picture of respectability. But when her shift ends, Edda is barely hanging on, desperate to forget the circumstances that cut her time overseas short. When she receives a panicked phone call from someone who utters the fateful code word “Brightwood,” Edda has no choice but to confront her past. With precious few clues and help only from Theo, a young man bearing his own WWI scars, Edda races to uncover what secrets may have followed her across the ocean.
