Love Anthony by Lisa Genova

Beth and Olivia are two women who live on Nantucket, but don't yet know how their lives will become entwined. Beth is in shock, picking up the pieces of her life after discovering that her husband has been having an affair. Olivia, meanwhile, has moved to Nantucket to try to escape the memories and pain of her young and profoundly autistic son Anthony's death and the resulting breakup of her own marriage. The reader gets to know Anthony through Olivia's journal entries about him and feels her grief in wondering what Anthony's life's purpose was.  Surprisingly, Olivia's answer comes from where she least expects it.  In Love Anthony, Genova has written a novel about a mother's encounter with autism that is honest and heartbreaking. For people who enjoy Elin Hilderbrand and Jennifer Weiner.  It will be published later this month.
