This book was sent to me by the publisher in exchange for an honest review. 
 WOOOOOOW this book blew me away. The ending stabbed me in the heart. (view spoiler)[ (pun intended) (hide spoiler)] 
 First, starting off with the characters. Callie was a great main character. I found her interesting and was really invested in her journey. Throughout this book, Callie is trying to escape her fate that was sent to her in her future memory...where she kills her sister. Since Callie has a kind heart and loves her sister, she does not want her memory to come true and does whatever she can to escape this fate. I honestly can say that she is one of the most compelling characters I've read about and I can't wait for more of her story in the sequel. She's such an admirable girl. 
 And then there's Logan, the love interest. This guy is really too perfect. If there's one thing that I have to critique this book on, it's that Logan should have had a bigger character flaw. One little thing that he was flawed at though was not standing up for himself. His brother took control of him too much and Logan never got to make his own decisions. So that wasn't too good. But other than that, I found him incredibly sweet and fell in love with him just as much as Callie did. 
 As for Jessa, Callie's sister, I wish there would have been more of her in the book since she isn't seen a lot. But she is mentioned a lot by Callie. I think if this book was written in multiple perspective, we could have gotten to know her a bit more. But from what I did learn from her, she seems like a sweetheart and I agree with Callie that I couldn't picture myself ever killing her. 
 The world building was good. Not as fantastic as other dystopian world buildings I've read about but one thing I appreciate is that the world was easy to understand. Often times, world building goes over my head and it gets frustrating when I can't grasp the concept. But I didn't have any problems with it in this book. In fact, I found it so interesting. The concept of receiving memories from your future self that helps you determine how your life is going to turn out, carrier wise, etc. is so intriguing and a unique genre and I think Pintip Dunn did this concept justice. Plus the amount of twists throughout this book were unbelievable. Specifically, the last ten pages had me on the edge of my seat! 
 One other reason why I think I liked this book so much is that the romance is heavily present. Most dystopian books have romance but I've never read one where the romantic storyline is just as present as the main one. And (being a romance fanatic) I really enjoyed that. The romance between Callie and Logan was beautiful and believable. At first it came off instalovey to me, but then I remembered that they've known each other since they were kids. It was just the fact that they hadn't spoken to each other for five years that made me think that. But it wasn't an issue. I was rooting for their relationship to work throughout the book. They had setbacks, but I loved how they seemed to find a way to work it out and be together. 
 In conclusion to this longest goodreads review I've ever done, I highly recommend to pick up this beautiful book. Thanks to BookTube Tours and Entangled Teen for sending me a copy! :)
