I picked this book yesterday because I was reading a blog post (which I don't recall now) and it had a reference to the book.

To quote from the blurb of the book

How can an 11-year old boy hear a Mozart fantasy for the first time and play it back note-for-note perfectly-but struggle to navigate the familiar surroundings of his own home? Cathleen Lewis says her son Rex's laugh of total abandon is the single most joyous sound anyone could hear, but his tortured aversion to touch and sound breaks her heart and makes her wonder what God could have had in mind. In this book she shares the mystery of Rex and the highs, lows, hopes, dreams, joy, sorrows, and faith she has journeyed through with him.

That, in short, sums up what the book is about. The length made it absolutely perfect for reading within the day. The prose isn't the best possible one. At places it does tend to repeat itself. However, the path of discovery, faith and hopes that it weaves is difficult to miss. It is, as mostly they are, an inspirational and uplifting story. A story of triumph, strength, faith and belief. And, that's why it is a recommended read.
