This book is rude!

Mum bought me the audiobook, it freaked me out at first, the voices are very realistic and the Dad shouts a lot, Mum explained that it's darkly humourous and that the boy has autism and it's written through his eyes and encouraged me to persevere, she has now found me a copy of the book, there is a lot of swearing in it!
I wanted to blip a page of text but Mum said no, if you could see it you would probably agree!
