Two sisters discover startling secrets in their mother’s old journal in this “poignant” novel by the New York Times–bestselling author of Garden of Lies (Debbie Macomber). Emily and Sarah Marshall are cleaning out their dying mother’s attic when Emily finds an old leather diary. Their mother’s handwriting on the yellowed pages takes them back to a small Nebraska town in the summer of 1951, where sheltered, almost-engaged Elizabeth Harvey is swept into a clandestine romance with AJ, her rebellious childhood friend. When AJ becomes the prime suspect in a neighborhood fire, Elizabeth has to make the most difficult decision of her young life and choose between passionate but unpredictable AJ and her stable, longtime beau, Bob.   Shocked to learn that their mother was in love with a man other than their father, Emily and Sarah must confront painful truths about their mother, their father, and ultimately, themselves. Moving and uplifting, with a surprise ending readers won’t see coming, The Diary is a novel about the mysteries of romantic love and the unassailable bond between parents and children.
