It was a fantastic, mind-blowing thriller.
I loved the story and the way Holly Jackson describes every event so well.
I ended reading 1 day ago.
It's an amazing book. Don't know why people are criticizing it, just for the adult rating of the book.
I recommend it to anybody looking for a good thriller.
I would like to say that its first half is really slow-paced paced especially the 2nd chapter and the Halloween party, where all characters are introduced.
Its ending is a heartbreak (heartbreak for me, meaning a sad ending).
the post "letter" part in the end was something an crime thriller reader like me can predict after the ending, if the person believes Billy wasn't the killer.
I would say it's a highly recommended book by me
