Ave, 

  Christopher's behaviors can seem mysterious at times, but I think it's still 
  possible to try to understand them and to feel empathy for him and all people 
  in the same situation.  I'm glad to see that you have come to some of that 
  kind of feeling toward Christopher.  Crossing that border of empathy is one 
  of the things we hoped everyone in CHQ would experience by reading this book.

  One writing issue you should think about is this:  Using paragraphs well 
  is important so that your readers will know when you are changing the
  subject or introducing something new.  Your paragraphs are generally
  quite long and they can contain several distinct points.  For instance,
  the sentence that starts "In Chapter 67 ... " is the beginning of 
  a new idea and the discussion of a new example.  So start a new
  paragraph there.  Similarly, later on in that mammoth second paragraph, 
  "There is only one moment ... " is another transition to a new point.
  Start another paragraph there.  
  
  Specific comments:

   (1) In your sentence, "Due to the fact that Christopher only had a few moments 
       of interaction with the officer he did not know that he was arresting a 
       child that was autistic and used hitting to stop people from touching him." 
       there are several things that should be changed.   You want the 
       "he was arresting" to be about the police officer, but the way this 
       is arranged, it refers back to the subject of that first clause, namely
       Christopher.  The best way to do this would be to put the "he" in the 
       clause and make the subject of the whole sentence be "the officer." 
       You also need a comma before the main part of the sentence.
       Moreover, it would be better to use "who" rather than "that" later on.
       since you are referring to people rather than things.  So something like:  
       "Due to the fact that he had only a few minutes of interaction with 
       Christopher, the officer did not know that he was arresting a child 
       who was autistic and who used hitting to stop people from touching him."  

   (2) "orange squash juice" sounds a bit strange.  In Britain, I think
       "orange squash" is actually a syrup mixed with water and used to 
       make non-carbonated orange-flavored drinks.   

   (3) page 2: The letters from his mother are the only sections in the novel
       not written by Christopher, so they are not in his voice.  But I think 
       we're still "in his head" in a way because we are essentially experiencing
       him reading them or copying them into his book.

   (4) Your discussion of how Christopher needs very specific instructions
       to do things is very good.  His misunderstanding of "stay out of
       other people's business" is also related to his dislike of and inability
       to understand metaphors.
