What I'm reading... Daniel Isn't Talking

I'm reading a fiction right now called Daniel Isn't Talking. Marti Leimbach is also the author of Dying Young, the book that was made into the movie that starred Julia Roberts. I'm only 50 pages into it, but I can already see that it's on the mark. Here is the excerpt taken from Amazon.ca:
From Publishers WeeklyLeimbach (Dying Young) notes on the back of the galley that she has modeled her title character on her own autistic son; the result is moving, frequently funny and never mawkish. The novel is narrated by Melanie Marsh, an American woman living in England who seems to have it all: Stephen, a rich if somewhat starchy husband; Emily, a vivacious daughter; and an adorable son named Daniel. But after a normal infancy, Daniel is beginning to behave strangely—throwing tantrums, walking on his toes, still seeking his mother's breast and refusing to talk. As Melanie unravels, Stephen remains in denial, until the dreaded diagnosis of autism is delivered. The marriage falls apart, but Melanie does not. She embarks on a frustrating, heroic mission to get the best treatment for her son, eventually entrusting his care to Andy O'Connor, a behaviorist with a dubious reputation. But his unorthodox methods get results, and soon, a bit too predictably, a romance blossoms between Andy and Melanie. While the novel lacks the literary ambition of The Curious Incident of the Dog in the Night-Time, Leimbach does succeed in making us care about Daniel and his progress. (Apr.)

I would really recommend it to anyone that is interested in understanding the difficulties that families go through. I wouldn't dare suggest that this book is the authority on how families cope or experience the reality of having a child with autism, but I can say that I really related to all of the emotions that the main character, Melanie, struggled with on the lead up and the after-math of receiving a diagnosis for her son.
