Eh. Not worth the hype. I put this down to go to bed right before the exorcism began, so you can imagine how riveting and tense I found this book. I love unreliable narrators and switching POVs and ambiguity … normally. One or two at a time. But I felt like this book never gave me a proper payoff to anything; it faded to black so often that the tension couldn’t be maintained. Just. Eh.
