 wow. 
 I knew it. I knew that was gunna happen and I don't know what to say. Like, I - what. 
 I was filled with fear and adrenaline as I read this book. Definitely had it's creepy factors. 
 The ending was slightly predictable but that's okay. But right now, instead of getting read to bed, I can't help but feel my pulse race. 
 Although I know it ended on a rather open-ended note, I'm a little confused. but that, in itself is a spoiler so I'll leave it down there. 
 (view spoiler)[ who warned them initially? and why in pieces? who was the lady in the bathroom? who wrote 6E on Murray's jacket? why did Antoine see a whole jet fly down with QU? Who was warning them? Is there something out there besides the doppelganger that is helpful? If so, why hadn't they helped? I wish we knew! (hide spoiler)] 
 I'm left with way more questions than answers.
