An intensely personal yet epic spiritual journey, The Horse Boy follows one Texas couple and their autistic son as they trek on horseback through Outer Mongolia in an attempt to find healing for him. When two-year-old Rowan was diagnosed with autism, Rupert Isaacson, a writer and former horse trainer, and his wife Kristin Neff, a psychology professor, sought the best possible medical care, but traditional therapies had little effect. Then they discovered that Rowan has a profound affinity for animals particularly horses and the family set off on a quest that would change their lives forever.
