I must say I was intrigued by this with the Netflix movie out and I'm glad I read the book. While the language in it is definitely not for the faint of heart, I liked reading with the stalker/killer's POV and what drove him to his madness/obsession. Yes Joe is crazy, stalker and obsessed with Beck. He kills people that are not good for her, he steals her stuff, he knows everything about her. Ending was not surprising. 3 stars.
