I give this book a rating of 3.

It was a very easy read, but it did not captivate me completely, and I found it very easy to put it down if I needed to. I was frustrated with a lot of the maths, and some of the tangents that Christopher trailed onto, and would skim or skip through those parts.

It certainly touched me emotionally, and even brought tears to my eyes (when Christopher realised that his mother wasn't dead). I also felt the fear and panic that Christopher felt, as he was trying to cope with being alone in the outside world - As it does indeed show that he feels things deeply, but is unable to express them.

I found it to be an interesting read, though not very challenging or captivating. However it was certainly unique to be reading from the point of view of someone with Aspergers.
