the book is amazingly disturbing that's how I'd describe it. It definitely says a lot about English colonialism and imperialism but also it shows how cruel human nature is ( I wouldn't want to spoil it for you in case you want to read it) and it's all portrayed through children which is actually very gruesome since children generally aren't supposed to act the way that they do in the book
you should definitely give it a try, the first chapter is a bit boring in my opinion but it's a fast paced nicely written book overall. I'm reading it in my native language (Macedonian) so I really can't comment on the writing style but I'll reread it in English just because why not
DISCLAIMER I really wouldn't recommend it if you're triggered by fatphobia , bullying and animal abuse since these are reoccurring themes throughout the book
