I knew going into this book that it wasn't 100% my normal tastes. A psychological mystery? With no... dragons? Or talking animals? Or hidden-but-obvious-from-the-first-page magical talents? But I needed to cleanse my palate a bit and I stumbled upon this book at work and thought, heck, I'll read it and its pretty cover. 
 It was underwhelming, really. The characters, though they had depth and personalities and I could tell them all apart, were just boring. I didn't care to read about them, which honestly would've been fine if I cared about the plot. But that was hard to do when I guessed the "twist" fairly early on. 
 (view spoiler)[ It's just... I was surprised when I watched the Uninvited, I was. I had strong suspicions when I read We Were Liars. But barely a quarter of the way into Vanishing Girls, I was convinced I was correct in my hunch. Perhaps had I not been exposed to similar plots before, I wouldn't have guessed at all. But sadly, I was, and I did. (hide spoiler)] 
 But like I said, this isn't my normal cup of tea and perhaps I let my own personal bias get in the way. I would certainly recommend this book to someone who does like realistic (albeit perhaps a bit predictable) psychological mysteries and doesn't mind a bland character or two.
