Query: Different, but painful to read

I have to admit that the book is very different. The funny illustrations throughout the book, and the story being told by an autistic boy. I was intrigued as to who killed the dog, but the answer was given away so quickly in the book. After a few chapters, I find the endless mathematical problems, and the run-on sentences irritating. I find myself skipping paragraphs just to get to the interesting part. I understand that what Christopher did is triamphant to autistic patients everywhere, but I really could care less. Some intersting storylines, but oversall there's really nothing to the book.
