A woman wrote to Gaiman telling him how her son, who has a has a visual processing disorder, taught himself to read with Coraline. He figured out how to translate the words in the book to auditory sounds that he could remember, and was then able to read in a way that made sense to him.
Over the years, this has given him the confidence to overcome a number of hurdles. He simply thinks back to teaching himself to read, after several adults had told him he never would, and he is reminded of how remembering you reading aloud gave him the idea to 'translate' written words into sounds... and he thinks outside the box to figure out a way around whatever he's having trouble with.
As I said, he's 12 now, and reading "Grey's Anatomy", the medical school textbook, for fun! He has decided to be a trauma surgeon.
I honestly don't think his life would have turned out this way if we hadn't taken him to your book reading.
So, thank you again for writing, for reading, and for changing my child's life.
Now that is the perfect example of a life-changing book.
