We first meet Melanie, the protagonist and narrator of Daniel Isn't Talking, at a particularly vulnerable point in her life. She's a new arrival in an unfamiliar country, having emigrated from the United States to England to set up house with her new husband in a cottage owned by his family; she's not working, and is dependent on her husband for both financial support and social ties; she doesn't really know her husband all that well, as she seems to have turned to him soon after losing her boyfriend at the time in a tragic motorcycle accident; and she has two small children, the elder of whom is four years old and, you might have guessed, can't talk.
It's soon made clear that young Daniel has autism, and on the heels of that discovery, all hell breaks loose in Melanie's personal life. Her husband abandons her, leaving her the cottage but cutting off his financial support of her. With no job, two children to feed, and Daniel's various expensive tests and therapies to pay for, she is soon reduced to selling off everything in the house that isn't nailed down.
The rest of the book is about how Melanie gets on her feet again, establishing herself independently in this new environment, finding the right therapist for her son, getting her daughter started in school, and falling in love. This story --- Melanie recovering from the shock of her husband leaving her, and finally getting past her grief for her lover, and starting to live for herself again --- is good enough, if a bit cliche.
Supporting characters make it more interesting, like Melanie's friend Veena, another immigrant (albeit from India, not the US), who works as a cleaning lady while studying philosophy. She is funny, interesting, supportive of Melanie and understanding of Daniel in ways that Melanie, mired in her angst, can't be. She also gives Melanie needed perspective: she reminds her, gently but firmly, that worse fates exist than having an abnormal child. (I wanted to stand up and cheer when she said that; Melanie's woe-is-me, my-son-is-broken act REALLY got on my nerves!)
That said, the Melanie/Veena relationship smelled uncomfortably like white-lady patronage to me. Melanie pays Veena to clean her house, though she is not very good at it; what Melanie is really buying is her conversation.
Another supporting character I liked was Melanie's brother, who is barely in the book at all but who intrigued me. He lives in the US and takes care of traumatized parrots. Melanie doesn't like him very much, chiefly because he doesn't help her in any way when she's on her own and broke. She is disgusted by the fact that he has so much empathy for his birds but none at all for her.
The biggest thing that bothered me about this book was its treatment of Daniel, and, through him, autism in general. See, Daniel is really not a character in this book so much as a plot device, a Thing Melanie Must See Through. It's kind of hard to articulate why I think he's objectified in the text, since the story belongs to Melanie --- I would be unreasonable to expect all Daniel, all the time --- but it seems like Marti Leimbach never gives any hint, not only of what Daniel is thinking or feeling at any time, but that he can think or feel at all. He seems reduced to a collection of sullen silences, bizarre behaviors and random temper tantrums. In this, the book compares really unfavorably with Keiko Tobe's manga series "With the Light," which tells a very similar story about a young mother and her autistic little boy, but in which both characters are portrayed with equal depth, nuance and sensitivity.
