I enjoyed this less than I thought I would have, but I still enjoyed it. I think there are 3 main reasons why this wasn't a 5 star for me.
1- The pacing was a bit off, I felt that we spent too much time with some scenes, and not enough with others.
2- The friendship of the characters never felt truly real to me; it felt more like telling than showing, so I never felt like I could truly "feel" the depth of their relationship. And that only worsened throughout the book to the point where in the 2nd half of the book, it felt like nothing anymore.
3- I was expecting it to be more mind-blowing in terms of the discussion of colonialism. Don't get me wrong, I think the writing was brilliant in terms of making you feel that constant dread that colonialism makes you feel when you slowly start understanding the reality of how things were. However, if you already have quite a good understanding of colonialism and its depth, then this book isn't so mind-blowing which is unfortunate. 
I feel bad for saying this, but I think once more books like these (that discuss colonialism in fiction like this) get published, I think this book will go under a little bit.

Either way, I think my expectations were simply too high. However, I still enjoyed it.
Although now I want to study more languages in depth.
