This book is written from the perspective of Christopher Boone, a 15-year-old autistic boy who lives in England. Author Mark Haddon shows an uncanny knack of getting inside the boy's head and relating things from his black-and-white world. His world must be orderly or Christopher has a hard time functioning. He does advanced math problems in his head in order to calm down in stressful situations. He is presented with a lot of stress when his parents disappoint him, each in a different way. He feels forced to make his way across England on his own to elude perceived danger and he overcomes situations which are fraught with frustration for him. His parents show a lot of compassion at times, but his idiosyncrocies sometimes get the best of them. This is an amazing book, which probably shows the reader more about the way an autistic person thinks than would many textbooks on the subject.
