Very engaging book. Simple writing makes it easy to read and with many short chapters which encourages you to keep reading.
The Netflix show is a very faithful adaptation, so if you enjoyed the series you will probably enjoy this book too. Although, book Joe is far more psychotic and delusional than his Netflix counterpart. Netflix Joe often seems a lot kinder as they added the child next door neighbour character and changed a few of the murder scenes to make it seem like Joe was defending himself (as a matter of fact, it was not self defense).
The book is much more intense, which I liked. However, constant mentions of social media threw me off. Being in Joe's head for a few days is a strange, psychotic trip that I don't plan on taking again too soon.
