The Horse Boy: A Father's Quest to Heal His Son by Rupert Isaacson is the story of a families incredible journey. In 2007, Rupert and his wife Kristen took their 5 year old son, who was prone to tantrums, had poor language and social skills and wasn't potty trained on the trip of a lifetime across Mongolia. From when he was a baby, they knew that something was not right with the boy.
I highly recommend reading this book so that readers can experience the intensity of parenting a child with autism, to empathize with its impact on a marriage and admire the force of love that propelled such a journey, book and soon to be movie.
Hurry up and read it before the movie comes out!
