No One You Know — Michelle Richmond

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.
