Solid book, I liked it a lot. 

I like stories like this, and I listened to the Audio book which really helped immerse me in the story, I had read this one years ago but I had mostly forgotten the story. 

I found Christopher to be a strong main character and I really enjoyed seeing the world through his perspective. It must be really scary to not understand what is going on a lot of the time but also to by hyper intelligent in other ways. 

I like how he used maths to make sense of a world that really doesn't hold much in the way of structure. 
I also enjoyed that it wasn't just a  "they all live happily ever after" ending, it left it open and if felt honest and real. 

Christopher's Parents, I did sympathise with them, however I did think that they were pretty shitty parents overall, and there was a lot of questionable moments, and the losing of tempers turning into violence against a child who is so very much on the spectrum felt uncomfortable, and more so that it was from Christopher's perspective.
