All her life Ellie Enderlin had been known as Lila’s sister—until the day Lila, a top math student at Stanford, was murdered, and the shape of their family changed forever. Twenty years later, Ellie is a professional coffee buyer who has never put down roots. When, in a chance meeting, she comes into possession of the notebook that Lila carried everywhere, Ellie returns home to finally discover the truth about her sister’s death—a search that will lead her to Lila’s secret lover, to the motives and fate of a man who profited from their family’s grief, and ultimately to the deepest secrets even sisters keep from each other. From the bestselling author of The Year of Fog (“Highly recommended [for fans of] authors like Jodi Picoult and Jacquelyn Mitchard.”— Library Journal [starred review]), this is a riveting family drama about loss, love, and the way hope redefines our lives—a novel at once heartbreaking, provocative, and impossible to put down.
