I struggled with this book. It just didn't make sense to me that someone would take his autistic son and his wife all the way to Mongolia for shamanistic healing. It was heartbreaking how difficult their lives are and how far they'd go for their child's benefit. Then I saw the movie and it all became clear. It finally made sense. In the book, the author comes off as someone who is trying to prove to the world that it's not his fault that his son has autism. But in the movie, you can clearly see that all the travel and work and hardships are out of love. It is beautiful.
