Love Anthony - Lisa Genova
Another good book by Lisa Genova. Once you start you'll want to finish it as soon as you can.

Love Anthony tells the story of Olivia, whose eight-year-old autistic son has passed away. She comes to Nantucket to find some answers to questions that have been nagging at her about Anthony. "Why my son?" "Why my family?"

It also tells the story of Beth, a stay-at-home mom who is recently separated from her husband after finding out about his cheating. Alone, she rekindles her passion for writing. A passion she can share with Olivia.
