This was one of those few books that earned its 5-star rating for me. There was so much depth and emotion throughout that I just couldn't help devouring it. 
 Echo and Noah's stories were both so rich and layered and heartbreaking, it was hard not to fall in love with both of them instantly. I have a thing for broken characters and these two were some of the most broken I've read. 
 Echo and Noah as a couple were amazing. I loved everything about them together. Both of them were mostly selfless with each other and highly protective, especially Noah. God, Noah. 
 It's no secret that my book boy "type" is usually broken, protective, bad boys with tattoos. And Noah? He has it all. He could be such a douche at times but then would turn around and be amazingly sweet. I loved him. Everything about him. And the way he treated Echo? Ugh, heartfail. Love, love, love, love, love. 
 Echo was definitely one of the most tortured heroines I've ever read. What happened to her was so incredibly horrible, yet she dealt with it the best she could. The author did a wonderful job portraying the emotional trauma and resulting breaks that happened. I could almost feel what she was going through each time. 
 All in all, I loved this story, everything about it. It's not often you read a book that really makes you feel what they characters feel. This was one that did for me. I almost cried at one point, which is saying something. I would recommend this book to anyone of the older, young adult sect. It does have some things that are tough to stomach, so just be prepared.
