I'll be honest, and admit I don't really read thrillers very often these days. I might, therefore, have a slightly malformed idea of what constitutes thrilling, but for me this book didn't get anywhere near it. 
 I once had a conversation a few years ago with someone about music, and he mentioned a recently released record and said "It's basically for people who used to like Sade. High culture for the uncultured". 
 I thought at the time that that was incredibly sneering, and I'll be honest, it was, but at the same time, I couldn't help admitting that he had a point. 
 This book struck me as pretty much like a modern day, literary Sade album. 
 Loads of people will like it, loads of people will buy it, it'll get lots of coverage. There isn't anything really horrendous about it, it is not going to make people really angry or get people engaged in heated debate about it. But at the same time, there isn't really anything new, exciting, or even particularly notable about it. 
 The obvious point of reference for it is the aforementioned Gone Girl, and there are clear similarities. 
 I read Gone Girl last year and thought it was 3/4 of a really good book. It lost that 25 percent on the basis that the ending was truly awful, just utter rubbish. 
 I read the hullabaloo about this book, read the Gone Girl mentions, and fancied a quick read so thought I'd see how it matched it. It was certainly a quick read, a day from start to finish, which I guess is a tick in the positives column. 
 Don't get me wrong, it was an enjoyable enough way to pass a day or so, but it was just so utterly unremarkable. 
 A not particularly thrilling plot, featuring not particularly convincing characters, conveyed in a not particularly brilliant way 
 Normally, when I write a review on here, I'll at least spend some time on it and outline my thoughts, but with this one I have pretty much nothing more to say about it. 
 So, there you go. As I said, utterly unremarkable. 
 I'm off to dig out my Sade albums.
