Also spoilers ahead here.
I’ve read it, and i completely agree. The plot is quite sluggish, and after i was finished reading, i wished that i would have dropped it halfway through. The last third, is basically graphic descriptions of torture. And i wouldn’t have needed that to get the point of the book. I don’t need a happy ending. This isn’t what the book is about. But i also don’t want 150 pages of literal torture.
