House Rules by Jodi Picoult

I have read 3 other Jodi Picoult books, and have always been blown away by the ending(s).  This was the only book where I predicted the end result.  I kept waiting for a crazy ending, but it never came.  So in the end I was a little disappointed. 
Yet, I did lean a lot about Autism and Aspergers Syndrome.  In fact I grew to love the characteristic of an Aspergers kiddo.  This story was about a 18 year old Aspergers boy, Jacob, who loved forensic science.  He also loves his college social skills tutor.  But one day she is found dead in her bathroom and the evidence falls onto Jacob, or does it????
