** spoiler alert ** 
 My wife likes mysteries, it appears I like mysteries. She has an audible account and listens to about 2 books a month. About 5 or 6 times a year she'll tell me I really need to listen to one of the books she's listened to. Some of my favorite novels in the past couple of years came from her recommendations. And yet, every time she recommends something to me - EVERY. SINGLE. TIME. - I balk at her request. "Honey, that's sooo lame," or "Um, you know I'm a man, right?" 
 I tend to not want her to answer that last question. 
 But the point is that she almost never steers me wrong, and I still have to have my arm twisted into doing something I enjoy. I hate to think how she feels when she tells me I need to do something that I won't enjoy. 
 Regardless, I 'read' the book. It was often frustrating, and I seldom stopped listening and didn't feel antsy. This tends to crawl into your head and make you think about it when you aren't reading. You don't consume it... it consumes you. 
 This is a masterful piece of work. I'm going to put a spoilerific filled ramble below. And be forewarned - spoilers will ruin this book for you. Really. It's probably worth reading if you have half an inkling to do so. So please, if you intend on reading this, ever, then don't read any further.

 I don't like anyone in this book. Well, of the viewpoint characters, of which there are only two, neither of them is someone I can easily get behind and root for. The first half of the book is dedicated to painting Amy as a saint and Nick as a jerk - then the second half is about reversing that. I don't consider myself an particularly insightful reader, but I do try my best to figure things out very early and then compare how well my predictions line up with the events as they occur in the book. 
 In this case, I'd figured out the twist relatively early. We have the bad guy that is good and the good gal that is bad, and both are unreliable narrators. He's a liar, a cheat, and a coward. She's beautiful, selfless, loved by all, and kind... except that's not true. She's missing and presumed dead, murdered by her sonofabitch husband. All the evidence makes it look like an open and shut case. 
 As an aspiring author, the tricks used to pull me in, to make me believe something, the misdirections... they're brilliant. I would almost consider this a case study on how to write the perfect mystery novel. But for me, the joy I get in figuring things out only gets me so far. The big 'twist' isn't really part of the novel's climax, but is revealed about half-way through. Where it changes form a closed mystery to an open one. We go from wondering who did it to wondering if she will get away with what she's done. 
 And it's beautiful. I mean that it's compelling reading. I do start feeling sympathy for Nick as the book progresses, but it takes a very long time for that to happen. I didn't trust Amy from the very beginning. 
 And there is still that little sting of the ending. I found it a little lacking. Not the resolution I'd hoped for. No resolution at all really. In fact, it was an ending that I thought might work better in a movie than in a novel. But here, well, I'm not sure what to think about it, except that I felt it too bitter. 
 Oh, and that I can't stop thinking about it.
