This book has a very unique concept. Like the fact that there is only one love interest the entire way. Though I did find the imprint thing kind of weird and creepy. Like, hello, instant love? Really? But I guess it kind of makes scene for the context of this book, and it does make it unique. I actually ended up really enjoying imprint and soul mate thing after reading about a quarter to a third of the book. After all, it does explore concept that we normally would not have look at if not mentioned to us. 
 "Imprints don't make mistakes, Maggie. All an imprint is, is our souls seeing what's perfectly right for it in someone else. In here," he palmed his chest "I saw something in you that I couldn't live without. I chose you, inside of me, and you chose me. It's not one sided, it only works when both people imprint on the other. You are perfect for me in every way. I don't want to scare you with it all. I mean, you're so young and you don't know me. Yet. But...we will always be drawn together. We'll always crave each other. We'll always be in tune with each other, physically and mentally. There is nothing that can change or break that. And even if there was, I wouldn't want to. Not for the world." 
 At first when I started the book, I kind of felt creep out by the fact that Caleb and Maggie have to contently have body contact (holding hands, hugs, etc...) in order to stop the pain. And how they could not move away from the other if the other did not insure him or her that they will see each other again. Also, to be honest, I'm actually quite scared by the intensity of their relationship. Sure, I got that you are soul mates, but do you really have to move so fast? 
 I also felt really bad for Kyle in parts of the book. For crying out loud, he has loved her for two years. Two long years. He waited just so that he would get the chance to take her out. And when she finally agrees, the same night she got imprinted with his cousin/best friend. And through the entire date, she is only thinking about his Caleb, and not him. I felt really bad for him when reading that part. Though I got to admit that at first I only think that he probably only has a small crush on her, and that would fade away soon, but to know that he actually loved her- loved her for two whole years- make my heart break for him. And I hope that he'll be able to find his significant soon too. 
 I do have to say that Caleb really grow on me through out the book. He is just so sweet, kind and caring for her. By the end of the book, I'm a complete fan of Caleb. Really enjoyed his character. And seriously? Some of the stuff he says is just so amazing and sweet, which make me like him even more. 
 It's rooted in my blood to consume you and be consumed by you. To protect you. To please you, in every way. His fingers raked through my hair. To make you shiver when I touch you. And to his enjoyment, I shook with goose bumps. He smiled and skimmed his fingers down my arm. To cause your heart to beat faster. He tapped his finger over my heart as he'd done once before and it didn't make me calm down any more than it had before. To make you happy , to do anything and everything with you, to date you, spoil you, love you...marry you. So yes, I want to make love to you. I want to mutualize with you. I want to live with you. I want to marry you and have kids with you. But not today. Not right this second. We have all the time in the world, Maggie. I told you in the very beginning that I'll let you set the pace and that still stands. I'm ready for anything, whenever you are but I'm not pushing you, ok? I've waited this long for you and I'm happy. 
 Our main character, Maggie was also an amazing character. She is strong, sweet, and caring for everyone. Seriously. She even have concern for people who meant her harm. Even when they tried to kill her. I found that very remarkable. I also liked the fact she does not just blindly believe in the imprint. In fact, she even question about it. Like if her feeling are real, or is it just because of the imprint. I really liked that aspect of her. It made the entire soul mate thingy more believable. 
 I still felt tense and apprehensive, I had no idea what it was really or what it entailed or what it would feel like but this was Caleb. I had to stop thinking of him as just a boy. He was mine, for life, my soul mate, my significant. There was nothing to fear with him. He was always careful and loving with me and he would be with this too.
