I'd give this 4.5. such a raw and read migrant story. it is really emotional even though you know there must be some kind of happy ending for him to have written the book. truly eye opening.

for being written from the perspective a 9 year old you really get the feeling of waiting, boredom, pain, etc. the writing is very well done. 

I only wish that final "epilogue" type chapter was a tiny bit longer.
