I don’t usually gravitate towards psychological thrillers. I’m unsure about the reason. I enjoy them, even if a majority of the time I figure out the plot before it’s revealed. Things unfolded slowly and kept me guessing. The only part that felt rushed to me is the obligatory explanation of the villain’s backstory. It seemed to come out of nowhere, but it explained a lot and allowed for the book to progress as it did.
No real self-respecting book lover abuses books. By abuse, I mean crack the spine, mark it up, rip pages on purpose or by accident, toss around carelessly, and most definitely do not dog ear pages. Only monsters do that.
