I found this one super hard to read, it seemed much darker than the others. Far fewer – if not no likeable characters; which is fine, because they were well written, but it made my reading slow as result. I just needed a break from them. 
The ending is something I'm going to be mulling over for a while, verrry different from the film, and I'm still undecided if I found it believable, but then it was definitely memorable.
