The Perfect Son - Barbara Claypole White

Full-time mother Ella devotes all her time to caring for and protecting Harry, her son with Tourette's and ADHD. Husband and father Felix spends all his time working. When Ella has a heart attack it turns their lives upside down. She can no longer care for Harry, Felix has to become a parent, and Harry worries about his mother while trying to impress his father and figure out his future.

The ending was not very well crafted at all. Some parts dragged on and on.
