Initial Impressions 10/18/17: I can't even... what??? This book was not at all what I expected and without heading into spoiler-town (yet), I will say that I went through an array of feelings while reading it. Well hell, the book isn't what I expected while reading it either. It was just... well-done, Mindy McGinnis. You have slayed me. 
 Okay, so avoiding spoilers for now, here's what I can tell you about this book: it's about a girl named Sasha who is the good girl, won't even swear, is extremely dedicated to her music (clarinet) and works hard to the point of obsessing over being perfect with music, grades, and being good. Things start to take a turn when she discovers that she is (used to be) a twin, but her sister was never actually born and was absorbed in the womb. This is an actual thing that happens sometimes so okay. Sasha seems shaken by this information and tries to gather more information about her sister-that-could-have-been and things start to go haywire as she becomes entangled with a boy named Isaac, the stereotypical bad-boy with whom Sasha would never interact... except she has, and Isaac has proof. Sasha tries to figure out how and why and then we head into the twisty part of this book... (spoilers later) 
 So up until this point, I was like eeeeeeehhhhahhhahhh I don't know about this. I wasn't super keen on the twin-thing being a big part of the story because I didn't see that coming (yes, I KNOW it's in the synopsis -- reminder 184300495 that I go into books blind so I can be so very surprised by things like this and usually it creates for an even more amazing story because it was definitely a reveal that I was surprised by instead of knowing it was coming. See?) and like the obsessive person that Sasha is, she starts to take the investigation of her sister a little too far and takes on a little too much. 
 Okay, so let's head into spoilerville because OH MY GOD. (view spoiler)[ So here we go. Things start to get insane AF when Sasha starts blaming her missing time on her twin sister. Oh, yes. She's convinced that she absorbed her sister not just in a physical sense but IN A MENTAL SENSE. She believes that her sister's heart is the one fueling her body and who has fallen in love with bad-boy Isaac when from an outsider's standpoint, we obviously see that this sister is a psychological break that Sasha uses to allow herself to NOT be the good girl anymore and really do anything and everything she's ever wanted to do. So even still here, I was like eeehhhhhaahhhheee mehhh I'm not so sure about this. I mean, it's pretty messed up but it kind of headed into the bizarre with Sasha actually talking to her sister via computer/text/word docs when her sister's messages would appear back to her and her dedication to this idea that she really did absorb her sister mentally. 
 BUT THEN. The book takes a whole NEW twist and things get even freakin' weirder. I won't go through the whole plot of the book because I guess I should leave something for you to read but it becomes even more messed up and fascinating all at the same time as Sasha blames every wrong-doing on her sister and continues to grow colder as Sasha herself. She's so convinced about her sister existing within her that she's really able to blame anything on her and as she continues to grow colder as a person, she loses even more of that human touch, of which she had so little in the first place. Long story short, the book ends with Sasha trying to triumph over her sister, knowing she has to stay alive in order to stay dominant and her sister has gotta go and she tries to CUT HER OWN DAMN HEART OUT to give to Isaac since it's her sister's heart, the one who loves him. WHAT THE ACTUAL FUCK, MAN. It was so incredibly fucked up and... I kind of loved it? It was so shocking and so insane and I was just shaken to my very core. 
 The book ends with some conclusions and another bit of an open-ender, showing you that Sasha has kind of gotten away with her master plan and that things won't stop here. It seems like the beginning of a serial killer story or something because let's be honest, Sasha obviously suffers from a number of psychological disorders and since I didn't end up minoring in psych like I wanted to, I can't quite pin down which but it's either anti-social personality disorder, dissociative identity disorder, schizophrenia, or all three combined. The break shown in this story's timeline came out in full-force and it was shocking to watch Sasha unravel like that. (hide spoiler)] 
 The book truly shook me with its ending but there were also parts that were just plain weird. It ended up totally coming together but I must admit that I was kind of like oooooookay for a few good sections of the book where I wasn't sure how I felt. This book is one to mess with your head and your emotions and even if you're not crazy about the beginning, it's so worth finishing because you won't want to miss that ending!
